A porous balloon has a volume of 2.00 m³ and contains air at a temperature of 10.0°C and a pressure of 1.11×10³ Pa. When heated to 150°C the volume expands to 2.30 m³ and 5.00 % of the gas is observed to escape. Based on this information and assuming that the gas behaves as an ideal gas: A. How much gas was in the balloon at 10°C? Express the result in moles and kilograms. B. What is the pressure in the balloon at 150°C? Note: The molecular mass of air take it as 29.0 g/mol.
