Answer to Question #328017 in General Chemistry for myra

Question

If 2.0 grams of carbon react completely with oxygen, how many grams of carbon dioxide can be produced?

Answer 1

m(C) = 2.0 g;

M(C) = 12 g/mol;

M(CO₂) = 44 g/mol;

n(C) = m(C)/M(C) = 2/12 = 0.167 mol;

C + O₂ = CO₂;

By the chemical reaction:

n(CO₂) = n(C) = 0.167 mol;

m(CO₂) = n(CO₂) * M(CO₂) = 0.167 * 44 = 7.3 g.

Answer: 7.3 g.
