Question

What pressure will be exerted by 25.0 g of carbon dioxide at a temperature of 27.0°C and a volume of 500 mL?

Answer 1

P = 28.1 atm

Step-by-step explanation:

Given data:

Mass of carbon dioxide = 25 g

Temperature = 27.0 °C

Volume = 500 mL

Pressure = ?

Solution:

Number of moles = mass/ molar mass

Number of moles = 25.0 g/ 44 g/mol

Number of moles = 0.57 mol

PV = nRT

P = nRT/V

P = 0.57 mol × 0.0821 atm.L.mol⁻¹.K⁻¹ × 300 k/ 0.5 L

P = 14.1 atm. L /0.5 L

P = 28.1 atm
