The number of mole of air in the ball, given that the volume of the ball is 5.2 litres is 0.13 mole (Option A)How to determine the number of mole of airWe'll begin by listing out the given parameters from the question. This is given below:Pressure (P) = 61 kilopascalsVolume (V) = 5.2 litresTemperature (T) = 32 °C = 32 + 273 = 305 KGas constant (R) = 8.314 L.KPa/Kmol Number of mole (n) =? From the above parameters, we can obtain the number of mole as followPV = nRT 61 × 5.2 = n × 8.314 × 305317.2 = n × 2535.77Divide both sides by 2535.77n = 317.2 / 2535.77n = 0.13 moleThus, the number of mole is 0.13 mole (Option A)Learn more about number of mole:https://brainly.com/question/16259909#SPJ1
