Answer to Question #146026 in General Chemistry for alyen

Question

how many grams of o2 is needed to produce 37.5 g of co2?

Answer 1

Writing the equation for the complete combustion of carbon ,we have;

C + O2---------CO2

Molar mass of O2=16g/mol

Molar mass of CO2=44g/mol

If 16g of O2 produce 44g of CO2

Then the mass of 02 that will produce 37.5g of CO2=16×37.5/44=13.6g
