Answer:

Step-by-step explanation:

first, you calculate the amount of O2 in moles:

98.0 ÷ 32 = 3.0625

second, the ratio if O2/C3H8 is 5 so you need to calculate O2 in moles with that:

3.0625 ÷ 5 = 0.6125

third, the amount of CO2 in moles also can be calculate by the ratio of C3H8/CO2 which is 3

0.6125 × 3 = 1.8375

then multiply CO2 in moles by its molar mass which is 44 g/mol

1.8375 × 44 = 80.85g
