Question:

How many moles of gas would be present in a gas trapped within a 0.1 L vessel at
25.0 °C at a pressure of 2.50 atm?

Answers

Answer:Number of moles  = 0.01 moleExplanation:Given data: Volume of gas = 0.1 LNumber of moles = ?Temperature of gas = 25.0°C Pressure of gas = 2.50 atm Solution: The given problem will be solve by using general gas equation, PV = nRT P= Pressure V = volume n = number of moles R = general gas constant = 0.0821 atm.L/ mol.K  T = temperature in kelvin Now we will convert the temperature. 25+273K = 298 K by putting values,2.50 atm × 0.1 L = n × 0.0821 atm.L/ mol.K  × 298 K 0.25 atm.L = n × 24.47atm.L/ moln = 0.25 atm.L /24.47atm.L/ moln = 0.01 mol
