Answer 1

$\huge  \underline{{ \overbrace {{\underbrace{\mathtt\red{ᴀ} \mathtt\orange {ɴ} \mathtt\pink{S} \mathtt\green{ᴡ} \mathtt\purple{ᴇ} \mathtt\blue{ʀ}}}}}}$

56 Litre

$\huge \sf \red {Explaination:-} \\ \\ \sf$

Molar mass =2×vapour density=2×8=16gm

No of moles =40/16=2.5

So volume =2.5×22.4=56 litres
