Answer 2

Answer:

One of the equations to calculate moles is-

Moles= Mass/Ar or Mr

You can rearrange this equation to-

Moles x Mr = Mass

Mr of oxygen= 16

Since it is a molecule, it consists of 2 oxygen atoms

So, in this equation, you use 32 as the Mr.

Moles= 10 (as given in the question)

10 x 32= Mass

320= Mass
