When acetylene, C2H2, burns in oxygen, high temperatures are produced that are used for welding metals.
2C2H2(g) + 5O2(g) →→ 4CO2(g) + 2H2O(g)
How many grams of carbon dioxide are produced when 173.3 grams of acetylene is burned?
Homework Answers
Number of moles of C2H2 = 173.3 g / 26.04 g/mol = 6.66 mole
From the balanced equation we can say that
2 mole of C2H2 produces 4 mole of CO2 so
6.66 mole of C2H2 will produce
= 6.66 mole of C2H2 *(4 mole of CO2 / 2 mole of C2H2)
= 13.3 mole of CO2
mass of 1 mole of CO2 = 44.01 g so
the mass of 13.3 mole of CO2 = 585 g
Therefore, the mass of CO2 produced would be 585 g
