Answer:

V = 3.89 L

Explanation:

Given data:

Mass of oxygen  = 5.024 g

Temperature = 28°C (28+273 = 301 k)

Pressure = 0.988 atm

Volume occupy by oxygen = ?

Solution:

PV = nRT

We will calculate the number of moles;

Number of moles = mass/ molar mass

Number of moles = 5.024 g/ 32 g/mol

Number of moles = 0.157 mol

Now we will calculate the volume,

PV = nRT

V = nRT/P

V = 0.157 mol × 0,.0821 atm.L /mol.K × 301 K / 0.998 atm

V = 3.88 L / 0.998

V = 3.89 L
