Question

Calculate the percentage by mass of nitrogen trioxonitrate (v)acid (h=1,n=14,o=16​

Answer 1

Answer:

The percentage by mass of nitrogen trioxonitrate (v)acid is 17.07 %

Explanation:

Formula mass = ca(NO₃)₂ = CaN₂O₆

Molecular Mass=Ca(40) + N₂ (2×14), + O₆ (6×16) = 40+28+96 = 164 amu

Mass of nitrogen in the molecule=28 amu

Percentage of nitrogen in the molecule=$\frac{28 amu}{164 amu}$×100=17.07 %
