Question

How many hydrogen atoms are present in 32 amu of methane?

Answer 1

Answer:

mass of one hydrogen atom = 2u

mass of one carbon atom= 12u

now no of atoms present in CH4

= 4

now mass of ch4 is 16u

therefore 32u is double the mass of the original ch4

therefore there would be double that is atoms of hydrogen

Answer 2

The number of hydrogen atoms in given amount of methane are $4.82\times 10^{24}$

Explanation:

The chemical formula of methane compound is $CH_4$

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

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

Given mass of methane = 32 g

Molar mass of methane = 16 g/mol

Putting values in above equation, we get:

$\text{Moles of methane}=\frac{32g}{16g/mol}=2mol$

1 mole of methane contains 1 mole of carbon atom and 4 moles of hydrogen atoms

According to mole concept:

1 mole of a substance contains $6.022\times 10^{23}$ number of particles

So, 2 moles of methane will contain = $(2\times 4\times 6.022\times 10^{23})=4.82\times 10^{24}$ number of hydrogen atoms
