The volume of a gas sample is 22.4 liters at STP. The density of the gas is 1.34 grams per liter.
lozanna [386]

Answer:

The mass of gas is 30.02 g.

Explanation:

Given data:

Volume of gas = 22.4 L

Density of gas = 1.34 g/L

Mass of gas = ?

Solution:

The given problem will be solved through density formula.

Density is equal to the mass of substance divided by its volume.

Units:

SI unit of density is Kg/m3.

Other units are given below,

g/cm3, g/mL , kg/L

Formula:

D=m/v

Now we will put the values in formula.

1.34 g/L = m /22.4 L

m = 1.34 g/L × 22.4 L

m = 30.02 g

The mass of gas is 30.02 g.
