Question

what is the relation between mass and volume of a gas at stp

Answer 1

Answer:

The volume of 1 mole of any gas is called its molar volume and is equal to 22.4 L at standard temperature and pressure. Molar volume allows conversions to be made between moles and volume of gases at STP. Gas density can be calculated from the molar mass and molar volume.

Answer 2

The relation between mass and volume of a gas at stp$\frac{m}{V}=\frac{M}{22.4}$

Explanation:

According to the ideal gas equation:

PV=nRT

P = Pressure of the gas = 1 atm    (STP)

V= Volume of the gas

T= Temperature of the gas =  273 K (STP)

R= Gas constant = $0.0821Latm/Kmol$

n= moles of gas =$\frac{\text {mass of gas}}{\text {Molar mass}}$

$1\times V=\frac{m}{M}\times 0.0821\times 273K$

$\frac{m}{V}=\frac{M}{22.4}$
