18 Holes on a Golf Course - I think the 'F' is wrong there.
18 h in g likely means converting 18 hours to grams, which doesn't make sense because hours and grams are units of time and mass, respectively. It's possible there was a mistake or misunderstanding in the question.
keep in mind there are 2 mol H in 1 mol H20 find the amount of g H in 6.527g H20 (6.527g H20)*(1 mol H/18 g H20)*(2 mol H/1 mol H20)* (1 g H/1 mol H) = .725 g H this the amount of H and the problem asks for % by wt of H in Hydrocarbon (4.626 g) (.725/4.626) * 100 = 15.79%
H: 1 g/mol O: 16 g/mol H x 2 = 2 g/mol O x 1 = 16 g/mol 2 g/mol + 16 g/mol = 18 g/mol
G=18 kJ/mol
