Question

How many moles of hydrogen are in 5.0 moles of ch4?

Answer 1

1 mole methane (CH₄) ------- 4 moles of hydrogen (H)
5 moles of methane -------------- X
X= 5×4 = 20 moles of hydrogen

:)

Answer 2

Answer: There are 20.0 moles of hydrogen atom in 5.0 moles of methane.

Step-by-step explanation:

We are given:

Moles of methane = 5.0 mol

The chemical formula for methane is
`CH_4`

By Stoichiometry:

in 1 mole of methane there are 4 moles of hydrogen atom.

So, moles of hydrogen atom in 5.0 mol of methane will be :

`5.0* 4 mol=20.0mol`

Hence, there are 20.0 moles of hydrogen atom in 5.0 moles of methane.
