Calculate the percentage of mass of all the component elements in sodiumtrioxonitrate(VI)

2 answers

molar mass of sodium nitrate is 85grams
atomic mass Na is 23g
atomic mass O is 16
NaNO3
Na%=23/85
N%=14/85
O%=16*3/85
There is no such thing as sodium trioxonitrate(VI).
%Na = [(mass Na/mass NaNO3)]*100 = ?
The others are done the same way
