Step-by-step explanation:

By the stoichiometry of this reaction if 5 mol natrium react, then 2.5 mol

N

a

2

O

should result.

Step-by-step explanation:

The molecular mass of natrium oxide is

61.98

g

m

o

l

. If

5

m

natrium react, then

5

61.98

l

=

154.95

g

natrium oxide should result.

So what have I done here? First, I had a balanced chemical equation (this is the important step; is it balanced?). Then I used the stoichiometry to get the molar quantity of product, and converted this molar quantity to mass. If this is not clear, I am willing to have another go.
