Since we need the mass percent, we need to know the molar mass of the entire compound:
H - 1g/mol
N- 14 g/mol
O -32 g/mol (16 g/mol x 2)
which equals 47 g/mol.
now, put the weight of the unknown, N, over the entire weight.
14/47 = 29.8 g/mol
Nitrogen: 93.2869%
Hydrogen: 6.7131%
The molecule of nitrogen dioxide contain 30,446 % nitrogen.
The oxide NO contain46,68 % nitrogen.
Nitrous acid is HNO2
There is NO symbol for nitrous acid. However it has the formula ' HNO2'. Compare with nitric acid Nitrous Acid = HNO2 Nitric Acid = HNO3 NB Note the number of oxygen present.
Nitrous acid
HNO2 is nitrous acid, a weak acid.
The acid with the chemical formula HNO2 is nitrous acid. HNO3 is nitric acid.
The acid with the formula HNO2 is nitrous acid.
NO2 is the polyatomic ionic compound nitrite Since it is bonded with hydrogen, this compound is an acid The correct name for HNO2, is therefore nitrous acid
HNO2 is nitrous acid. It is not to be confused with nitric acid, which is HNO3
