Question

How many moles do we have if we have 7.02 x 1024 molecules of

methane, or CH,, which is used to heat homes?

Answer 1

10 moles of methane

Step-by-step explanation:

1 mole of methane contains 6.02 × 10^23 molecules (Avogadro's number)

x moles should contain 7.02 x 1024 molecules of

methane

So,

x= 7.02 x 1024 × 1/6.02 × 10^23

x= 10 moles of methane
