1.	Find the number of moles of gas that would occupy 102 litres at a pressure of 3.7 atm and a temperature of 500 K.
Answer» 9.20 molExplanation:Given : Volume V = 102 LPressure P = 3.7 atmTemperature T = 500 KWe have to FIND NUMBERS of moles n : From ideal gas equation : P V = n R T = > R = 0.082 L atm mol⁻¹ K⁻¹Putting values in equation we get : 3.7 × 102 = n × 0.082 × 500= > n = 3.7 × 102 / 0.082 × 500= > n = 377.4 / 41 mol= > n = 9.20 molTherefore , number of moles of gas is 9.20 mol.
