1) You need to remember that at the same temperature and pressure, the volume of a gas is proportional to the number of molecules (or atoms for noble gases) which are in the gas. Chlorine and fluorine are both diatomic, so the ratio of their volumes tells you the ratio of the atoms in the product, and hence the formula.

2) Nitrogen (N2) has a molar mass of 28 g/mol, so 1.00 g is 3.57 x 10-2 mol.
From the molar mass of hydrogen you can similarly calculate the number of moles in 1.44*10^-1g, 2.16*10^-1g and 2.40*10^-2g. Comparing the number of moles of nitrogen to the number of moles of hydrogen gives a simple ratio in each case: the empirical formula of each compound. The law of multiple proportions is ...
