For the reaction C3H8+5CO2=3CO2+4H2O

Question

How many grams of co2 will be produced by buring 0.15 moles of c3h8?i thoink the ans is 16.2gco2

Answer 1

0.15 moles C3H8 x (3 moles CO2/1 mole C3H8) = 0.45 moles CO2.
0.45 moles CO2 x (44 gCO2/1 mole CO2) = about 20 g but you need to do it more exacting than that.
