Question

Calculate the mass of CO2 formed by the complete combustion of 2moles of C in sufficient oxygen?

Answer 1

Answer:

2 moles of carbon are burnt in 16 g of dioxygen.

16 g of dioxygen corresponds to

32

16

=0.5 moles.

Here, dioxygen is the limiting reagent.

It will produce 0.5 moles of CO

2

which corresponds to 0.5×44=22 g of CO
