Question
Calculate:
The volume of 4g of H2 at 4 atmosphere.
Solution
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
