Question

What is the percent composition by mass of hydrogen in nh4hco3

Answer 1

Answer: The percent composition by mass of hydrogen in given compound is 6.33 %

Step-by-step explanation:

We are given:

A chemical compound having chemical formula of
`NH_4HCO_3`

It is made up by the combination of 1 nitrogen atom, 5 hydrogen atoms, 1 carbon atom and 3 oxygen atoms

To calculate the percentage composition by mass of hydrogen in the compound, we use the equation:

`\%\text{ composition of Hydrogen}=\frac{\text{Mass of hydrogen}}{\text{Mass of compound}}* 100`

Mass of compound =
`[(1* 14)+(5* 1)+(1* 12)+(3* 16)]=79g/mol`

Mass of hydrogen =
`(5* 1)=5g/mol`

Putting values in above equation, we get:

`\%\text{ composition of Hydrogen}=(5g/mol)/(79g/mol)* 100=6.33\%`

Hence, the percent composition by mass of hydrogen in given compound is 6.33 %
