DiKsa [7]

I believe that the choices for this question are:

C2H4O2, C4H8O4 <span>
CH2O, C6H12O6 
C3H6O3, C6H12O6 
C2H4O2, C6H12O6 </span>

 

The answer to this based on the molar masses given is:

C2H4O2, C6H12O6 

 

To prove calculate the molar mass:

C2H4O2 = 2*12 + 4*1 + 2*16 = 60

C6H12O6 = 6*12 + 12*1 + 6*16 = 180
