Question

the mole percentage of O2 in a mixture of 7g of
N2 and 8g of O2 is? (ans:50%)

The number of moles of nitrogen = Mass of the given substanceMoalr mass = 728 = 0
25The number of moles of oxygen = Mass of the given substanceMoalr mass = 832 = 0
25Total moles = 0 25 + 0 25 = 0
5Mole % of oxygen = Moles of oxygenTotal moles  × 100                              =0
250
5 × 100                                       = 50 %
