Question

In an experiment, 12.0g of carbon gives 44.0g of carbon dioxide. What is the weight percentage of carbon in CO2?

*Skill: The weight percentage and mole percentage can be calculated if you know the chemical formula.

If you reduce 44.0 grams of CO2 to carbon, how many grams of C will you get?

Answer 1

Answer- given, Mass of C = 12.0 g, mass of CO2 =44.0

We know weight percentage formula,

Weight percentage =$\frac{mass}{total mass} × 100$ %

=$\frac{12.0 g}{44.0}× 100$ % = 27.3 %
