M o l e s space o f space C space equals space 84 over 12 space equals 7
M o l e s space o f space H subscript 2 space equals space 12 over 2 space equals space 6
M o l e space o f space O subscript 2 space equals space fraction numerator 56 over denominator 22.4 end fraction equals space 2.5

12 C subscript left parenthesis s right parenthesis end subscript space plus space 11 H subscript 2 left parenthesis g right parenthesis end subscript space plus space 11 over 2 O subscript 2 left parenthesis g right parenthesis end subscript space rightwards arrow with blank on top space space C subscript 12 H subscript 22 O subscript 11 left parenthesis S right parenthesis end subscript

M o l e s space o f space space C subscript 12 H subscript 22 O subscript 11 left parenthesis S right parenthesis space end subscript space equals space fraction numerator 56 over denominator 22.4 end fraction cross times 2 over 11

M a s s space o f space space C subscript 12 H subscript 22 O subscript 11 left parenthesis S right parenthesis end subscript space equals space fraction numerator 56 over denominator 22.4 end fraction space cross times 2 over 11 space cross times 342 space equals space 155.5 space g m
