Agas cylinder contains 2.50x103g of o2 (g)in
a volume of 10.0l. what pressure is exerted by the oxygen at20.0
oc?

188 atm

Explanation:

Given data

The molar mass of O₂ is 32.00 g/mol. The moles of O₂ are:

2.50 × 10³ g × (1 mol/ 32.00 g) = 78.1 mol

We can find the pressure exerted by the oxygen using the ideal gas equation.

P × V = n × R × T

P = n × R × T / V

P = 78.1 mol × (0.0821 atm.L/mol.K) × 293.2 K / 10.0 L

P = 188 atm
