Expert Answer:

Mass in grams for the following can be calculated by calculating number of moles.
left parenthesis 1 right parenthesis space 0.5 space m o l space o f space C a S O subscript 4
M a s s space i n space g space equals space M o l e c u l a r space m a s s cross times space m o l e s
space space space space space space space space space space space space space space space space equals space left parenthesis 40 plus 32 plus 16 cross times 4 right parenthesis cross times 0.5
space space space space space space space space space space space space space space space space equals 136 cross times 0.5 equals 68 space g

left parenthesis 2 right parenthesis space 0.25 space m o l space o f space C O subscript 2
M a s s space i n space g equals M o l e c u l a r space m a s s cross times m o l e s
space space space space space space space space space space space space space space equals space 44 cross times 0.25
space space space space space space space space space space space space space space equals 11 space g
