Question

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

What is the mass
of the gas sample, expressed to the correct number of significant figures?

Answer 1

The mass of gas is 30.02 g.

Step-by-step 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.
