Mass = 59.4 g

Explanation:

Given dа ta:

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
