Question

how many hydrogen atoms are present in 60 amu of ethane

Answer 1

Ethane:$C_{2}H_{6}$
One mole of ethane has 6 atoms of hydrogen and one mole of ethane has mass 30 amu.
Therefore 60 amu of ethane means 2 moles. This means 6×2=12 atoms of hydrogen.

Hope it helps.

Answer 2

The number of hydrogen atoms in given amount of ethane are $7.23\times 10^{24}$

Explanation:

To calculate the number of moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$

Given mass of ethane = 60 amu = 60 g

Molar mass of ethane = 30 g/mol

Putting values in above equation, we get:

$\text{Moles of ethane}=\frac{60g}{30g/mol}=2mol$

The chemical formula of the ethane is $C_2H_6$

1 mole of ethane is formed from 2 moles of carbon atom and 6 moles of hydrogen atom.

According to mole concept:

1 mole of a compound contains $6.022\times 10^{23}$ number of molecules.

So, 2 moles of ethane will contain = $(2\times 6\times 6.022\times 10^{23}=7.23\times 10^{24}$ number of hydrogen atoms
