Respuesta :
Answer:The percent composition by mass of hydrogen in [tex]NH_4HCO_3[/tex] is 6.32 %.
Explanation:
Molecular mass of the [tex]NH_4HCO_3[/tex] = 79 g/mol
Mass of the hydrogen atom present in one formula unit of [tex] NH_4HCO_3[/tex]:
[tex]= 5\times \text{(atomic mass of hydrogen)}=5\times 1 g/mol= 5 g/mol}[/tex]
[tex]\text{percentage of hydrogen}=\frac{\text{mass of the hydrogen in}NH_4HCO_3}{\text{molar mass of}NH_4HCO_3}\times 100[/tex]
[tex]\text{percentage of hydrogen}=\frac{5g/mol}{79 g/mol}\times 100=6.32\%[/tex]
The percent composition by mass of hydrogen in [tex]NH_4HCO_3[/tex] is 6.32 %.
