Answer: The percent composition by mass of hydrogen in given compound is 6.33 %
Explanation:
We are given:
A chemical compound having chemical formula of [tex]NH_4HCO_3[/tex]
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:
[tex]\%\text{ composition of Hydrogen}=\frac{\text{Mass of hydrogen}}{\text{Mass of compound}}\times 100[/tex]
Mass of compound = [tex][(1\times 14)+(5\times 1)+(1\times 12)+(3\times 16)]=79g/mol[/tex]
Mass of hydrogen = [tex](5\times 1)=5g/mol[/tex]
Putting values in above equation, we get:
[tex]\%\text{ composition of Hydrogen}=\frac{5g/mol}{79g/mol}\times 100=6.33\%[/tex]
Hence, the percent composition by mass of hydrogen in given compound is 6.33 %
