Question

Calculate:

The volume of 4g of H₂ at 4 atmosphere.

Answer 1

2 g(molar mass) H₂ at 1 atm has volume = 22.4 litres

So, 4 g H₂ at 1 atm will have volume = 44.8 litres

Now, at 1 atm(P₁) 4 g H₂ has volume (V₁) = 44.8 litres

So, at 4 atm(P₂) the volume(V₂) will be = `("P"_1"V"_1)/"P"_2 = (1 xx 44.8)/4`

= 11.2 dm³
