Answer:
Molar mass = 135.2 g/mol
Explanation:
Given data;
Mass of gas = 6.03 g
Volume of gas = 1.00L
Temperature = standard = 273 K
Pressure = Standard = 1 atm
Molar mass of gas = ?
Solution:
First of all we will calculate the number of moles of gas.
Formula
PV = nRT
1 atm × 1.00L = n × 0.0821 atm.L/k.mol × 273 K
1.00 atm.L = n × 22.414 atm.L/mol
n = 1.00 atm.L/22.41 atm.L/mol
n = 0.0446 mol
Molar mass:
Molar mass = mass/number of moles
Molar mass = 6.03 g/0.0446 mol
Molar mass = 135.2 g/mol
