Question

10 liters of a gas measured at STP weigh 19.64g calculate the molecular mass of the gas​

Answer 1

Given; 10l of gast at STP ;

• using ideal gas equation : PV = nRT
• (NOTE => 1torr≠1atm)

• 1torr ×10=(W/M) × 8.314 × 273
• 10 = 19.64/M × 22.7
• 100 × 100 = 227×1964/M
• M= 445828/10000
• M = 44.5828 g/mol.
