Question

pls solve this ques and give proper explaination ,if you can do it pen paper it would be very helpful pls...​

Answer 1

Weight of gas = 0.24 g, Volume of gas = 45 mL = 0.045 litre and density of H2 = 0.089. We know that weight of 45 mL of H2 = Density x Volume = 0.089 x 0.045 = 4.005 x 10-3 g Therefore vapour density.

$\frac{weight \: of \: certain \: volume \: of \: substance}{weight \: of \: same \: volume \: of \: hydrogen}$

$\frac{0.24}{4.005 \times {10}^{ - 3} } = 59.93$
