Four one litre flasks are separately filled with the gases \(\mathrm{\mathrm{H}_{2}, \mathrm{He}, \mathrm{O}_{2}, \mathrm{O}_{3}}\) at the same temperature and pressure. The ratio of the weights of these gases is
1 \(\mathrm{1: 1: 1: 1}\)
2 \(\mathrm{2: 1: 2: 3}\)
3 \(\mathrm{1: 2: 16: 24}\)
4 \(\mathrm{2: 1: 16: 24}\)
Explanation:
According to Avogadro's law, Number of molecules \(\mathrm{=}\) Number of moles of \(\mathrm{\mathrm{H}_{2}: \mathrm{He}: \mathrm{O}_{2}: \mathrm{O}_{3}=1: 1: 1: 1}\) Weight of \(\mathrm{\mathrm{H}_{2}: \mathrm{He}: \mathrm{O}_{2}: \mathrm{O}_{3}=2: 4: 32: 48}\) \({\rm{ = 1:2:16:24}}\)

The initial volume of a gas cylinder is \(\mathrm{750.0 \mathrm{~mL}}\). If the pressure of gas inside the cylinder changes from \(\mathrm{840.0 \mathrm{~mm} \mathrm{Hg}}\) to \(\mathrm{360.0 \mathrm{~mm} \mathrm{Hg}}\), the final volume the gas will be:
1 \(\mathrm{1.750 \mathrm{~L}}\)
2 \(\mathrm{3.60 \mathrm{~L}}\)
3 \(\mathrm{4.032 \mathrm{~L}}\)
4 \(\mathrm{7.50 \mathrm{~L}}\)
Explanation:
According to Boyle's law \(\mathrm{\dfrac{V_{1}}{V_{2}}=\dfrac{P_{2}}{P_{1}} ; \dfrac{750}{V_{2}}=\dfrac{360}{840}}\) \(\mathrm{V_{2}=1750 \mathrm{ml}=1.750 \mathrm{~L}}\)
