There are 85.63 g of CO2 gas in a container maintained at STP. How many liters of CO2 are there in that container?
konstantin123 [22]

Answer:

V = 48.64 L

Explanation:

Given data:

Mass of CO₂ = 85.63 g

Temperature = 273 K

Pressure = 1 atm

Volume of CO₂ = ?

Solution:

Number of moles of CO₂:

Number of moles = mass/molar mass

Number of moles = 85.63 g / 40 g/mol

Number of moles = 2.14 mol

Volume in Litter:

PV = nRT

R = general gas constant = 0.0821 atm.L/mol.K

1 atm× V = 2.14 mol ×0.0821 atm.L/mol.K  ×273 K

V = 48.64 atm.L / 1 atm

V = 48.64 L
