Areal gas is in a regime in which it is accurately described by the ideal gas equation of state. 27.1 g of the gas occupies 50.0 l at a pressure of 0.500 atm and a temperature of 449 k. identify the gas.

Argon

Explanation:

Given data

We can find the molar mass (M) of the gas using the ideal gas equation.

P × V = n × R × T

P × V = m/M × R × T

M = m × R × T/P × V

M = 27.1 g × (0.08206 atm.L/mol.K) × 449 K/ 0.500 atm × 50.0 L

M = 39.9 g/mol

If the gas is monoatomic, the one with a molar mass of 39.9 g/mol is argon.

yes it is balanced
