Answer:

Mass = 59.4 g

Explanation:

Given data:

Volume of CO₂ =32.5 dm³

Temperature = 32°C

Pressure = 104.7 KPa

Mass of  CO₂  = ?

Solution:

32+273 = 305 K

104.7/101 = 1.04 atm

PV = nRT

n = PV/RT

n = 1.04 atm×32.5 L/ 0.0821 atm. L/mol.K×305 K

n = 33.8 /25.04 /mol

n = 1.35

Mass of CO₂:

Mass = number of moles × molar mass

Mass = 1.35 mol × 44 g/mol

Mass = 59.4 g
