Calculate the volume of the gas, in liters, if 1.35 mol
Alina [70]

Answer:

22.8 L

Explanation:

Step 1: Given data

  • Moles of the gas (n): 1.35 mol
  • Pressure of the gas (P): 1.30 atm
  • Temperature (T): -6°C
  • Ideal gas constant (R): 0.0821 atm.L/mol.K

Step 2: Convert "T" to Kelvin

We will use the following expression.

K = °C + 273.15 = -6 + 273.15 = 267 K

Step 3: Calculate the volume of the gas

We will use the ideal gas equation.

P × V = n × R × T

V = n × R × T / P

V = 1.35 mol × (0.0821 atm.L/mol.K) × 267 K / 1.30 atm

V = 22.8 L
