the density of mercury is 135 gml what is the mass in kg of mercury that fills a 0250l flask


The Density of Mercury

The density of mercury is 135 g/ml. This means that for every 1 liter of mercury, there are 135 grams of mercury. Therefore, in order to fill a 250 liter flask, you would need 32,875 grams of mercury. Convert grams to kilograms and you have 32.875 kilograms of mercury.

The mass of mercury

To calculate the mass of mercury that would fill a flask, you need to know the density of mercury and the volume of the flask. The density of mercury is 135 g/mL, so to find the mass of mercury that would fill a 250 mL flask, you would need to multiply 135 g/mL by 250 mL, which gives you a answer of 33.75 kg.

The volume of the flask

The volume of the flask is 250 liters. The mass of mercury that fills the flask is 135 grams per milliliter multiplied by the volume of the flask, which is 250 liters. This equals 33,750 grams, or 33.75 kilograms.

How to calculate the mass

The density of mercury is 135 g/mL. This means that for every 1 mL of mercury, it weighs 135 grams. Therefore, to calculate the mass of mercury in a 250 L flask, we need to multiply the density by the volume.

The steps involved


To calculate the mass of a substance, you will need to know the density of the substance and the volume that it occupies. Once you have these two pieces of information, you can use the following equation to calculate the mass:

mass = density x volume

In this case, we are asked to calculate the mass of mercury that fills a 250 ml flask. We are also given the density of mercury, which is 135 g/ml. Therefore, we can plug these values into our equation as follows:

mass = 135 g/ml x 250 ml

After solving, we find that the mass of mercury in the flask is 33.75 kg.

The equation to use


To calculate the mass of something, you need to know its density and volume. The equation is:

mass = density × volume

So, for your example, the equation would be:

mass = 135 g/ml × 0.250 L

To solve this, you need to convert the units so that they match. In this case, you need to convert 0.250 L to milliliters (ml). There are 1,000 ml in 1 liter, so 0.250 L is the same as 250 ml. You can plug this into the equation and solve for mass:

mass = 135 g/ml × 250 ml
mass = 135 × 250
mass = 33,750 g
1 kg = 1,000 g, so 33,750 g is the same as 33.75 kg. This is the mass of mercury that would fill a 0.250 liter flask.

Why the density of mercury is important

The density of mercury is 135 g/mL, which means that mercury is 13.5 times as dense as water. This is why mercury is often used in thermometers, because it is a good conductor of heat and it is also a liquid at room temperature. Mercury is also used in barometers, because it is heavier than air.

The applications

Mercury is a chemical element with the symbol Hg and atomic number 80. It is commonly known as quicksilver and was formerly named hydrargyrum (/haɪˈdrɑːrdʒərəm/). A heavy, silvery d-block element, mercury is the only metallic element that is liquid at standard conditions for temperature and pressure; the only other element that is liquid under these conditions is the halogen bromine, though metals such as caesium, gallium, and rubidium melt just above room temperature. Mercury occurs in deposits throughout the world mostly as cinnabar (mercuric sulfide). The red pigment vermilion is obtained by grinding natural cinnabar or synthetic mercuric sulfide.

Applications

Mercury metal has a high volatility compared to most other metals. This makes it useful in thermometers, barometers, manometers, sphygmomanometers, floats, mercury switches,[17] mercury relays,[18][19] amalgam electrode potential alarm contacts for household security systems and other electrical applications where arcing between conductors must be prevented. Mercury readily alloys with other metals, forming amalgams with gold,[20] silver,[21][22] iron,[23][24] tungsten,[25][26] platinum,[27][28][29] palladium[30][31] and other metals. These alloys are used in dental fillings (“silver fillings”)[32], electrodes in fluorescent lamps or cathode ray tubes (due to their ability to block x-ray emissions)[33], switches for electrically powered Auxiliary Water Pump actuators on some European cars[34], some vaccines[35], anti-fungal agents such as thiomersal (ethylmercury thiosalicylate)[36], mercury-contaminated tattoo pigment,[37] certain sculptures such as those by Joseph Beuys[38], and Mexico’s La Flor de Pascua decoration[39].

The dangers


Mercury is a very dense metal. It is the only metal that is liquid at room temperature. When mercury is in its liquid form, it is shiny and silver in color. It is sometimes called quicksilver.

Mercury is found in nature, but it can also be released into the environment by human activity. When mercury is released into the air, it can eventually settle in water or on land where it can be taken up by plants and animals.

Once mercury gets into the food chain, it can build up in the tissues of fish and animals that people eat. Mercury that accumulates in fish and animals can be harmful to people’s health.
