The empirical formula of styrene is CH; find the % composition for H and CH. How many atoms are present in a 2.00 gram sample of styrene?

PLEASE HELP! THANK YOU

Sagot :

% Composition = ?
no atom in 2 g of styrene =? 
molar mass of strene =104.15
% composition of c= 12/13.008 =.922*100=92.2
% composition of h =1.008/13.008=0.0774*100= 7.74

no gram atom=mass in kg /molar mass=2/104.15 =0.01920 mol
no of gram atom * avogadro's number  = 0.0192*6.02 *10( exponent 23) =1.15584
