An ideal gas is at a pressure of 2.0 atmospheres and a temperature of 35°C. What is the molar density? A) 84 mol/m³ B) 79 mol/m³ C) 70 mol/m³ D) 67 mol/m³ E) 60 mol/m³

Question

Quizplus · Accepted Answer

The molar density of an ideal gas can be calculated using the ideal gas law: $ n/V = P/RT $. Converting 35°C to Kelvin gives 308 K. Using R = 0.0821 atm·L/mol·K and converting to m³, the calculation gives approximately 79 mol/m³.
