The volume will vary depending on pressure and temperature.
The weighted average molecular mass of air is around 28.97 g/mole. This comes from percent calculation of the substances in air, like nitrogen and oxygen mostly. To know the volume of air, you must first ask at what pressure and temperature? I will assume standard P and T.
If you want to know the volume of a certain weigh of air, first find how many moles of air you have by dividing by the above amount
which equals
1.726 moles. Once you have the moles (n) of air, use the gas law PV=nRT
where R is 8.206 *10^-5 m^3*ATM/K*mol (be careful with units)
. Solving for V, you get V=nRT
/P. Using standard pressure of 1 ATM (pressure outside) and standard temperature (298K), 50g (1.726) of air would occupy .0422 m^3.
This can be reversed to find how many grams of air is in a given volume.
This gas law is not accurate with polar species because of strong intermolecular interactions, and only applies to "ideal gases". These theories get very deep and complex in thermodynamics, and are way beyond this discussion; but at low pressures and temperatures this law is pretty accurate.

Does 500g of water occupy a space of 50ml?
Yes, 500g of water occupies a volume of 500ml, as 1g of water is equivalent to 1ml. Therefore, the volume of 500g of water is 500ml, not 50ml.
What is the density of 252ml and 500g?
Density is calculated using the formula Density = Mass / Volume. To find the density for the given values of 252mL and 500g, divide the mass by volume. Density = 500g / 252mL = 1.98 g/mL.
What is more dense a 200g sample zinc metal or 500g?
The 500g sample of zinc metal is more dense because density is a property of a material and does not depend on the amount of the substance. Density is defined as mass divided by volume, so for the same material, the one with higher mass will be more dense.
How many 500g in 3kg?
There are 6 units of 500g in 3kg. This is because 3kg is equal to 3000g, and 3000g divided by 500g equals 6.
The less mass in a given volume of air the what?
The less mass in a given volume of air, the lower the air density. This means the air is less dense, or lighter, in that volume compared to air with more mass. Air density affects various aspects of weather and climate, such as air pressure and the formation of clouds and precipitation.
