You want to store 147 g of C02 gas in a 145L tank at room te

You want to store 147 g of C02 gas in a 14.5-L tank at room temperature (25 °C). Calculate the pressure the gas would have using the ideal gas law (For CO2, a = 3.59 atm . L2/m012 and b = 0.0427 L/mol.) Real = ideal = atm

Solution

PV = nRT

V = 14.5 L

n = 147 g/ 44 g/mol => 3.34 mol

R = 0.082 L.atm/mol.K

T = 25 + 273.15 => 298.15 K

P = 3.34 mol x 0.082 L.atm/mol.K x 298.15 K / 14.5 L

P = 5.63 atm
