Assuming same pressure in each case, calculate the mass of hydrogen required to inflate a ballon to a certain volume V at 127°C if 8 g of He is required to inflate the balloon to half its volume, at 27°C.
Please explain the solution well.
Explain why? (a) The number of atoms in a certain volume of hydrogen is twice the number of atoms in the same volume of helium at the same temperature and pressure. (b) When stating the volume of a gas, the pressure and temperature should also be given. (c) Inflating a balloon seems to violate Boyle's law.
