# Question Query. watch

1. Stuck on the following question, anyone able to help?
'Squalene is a naturally occuring oil present in shark liver oil. A 0.100 mol sample of squalene reacted with 14.4 dm^3 of hydrogen, measured at r.t.p to form a saturated hydrocarbon C30H62.
(i) Calculate how many double bonds there are in each molecule of squalene.
(ii) Suggest the molecular formula of squalene.'
2. How many mol of H2 is 0.1 mol of it reacting with?

Hey

i) 0.1 mol reacted with 14.4 dm^3 of H2. 1 mole of hydrogen has a volume of 24 dm^3. So n=14.4/24= 0.6 mol of hydrogen
So each squalene reacts with 6 H2 molecules. So there must be 6 double bonds.

Ah yes. Thanks for your help mate!
