answer and explanation

to determine the percentage by mass of N on methyl orange.

We must first calculate the molar mass of methyl orange:

Carbo: 14 x 12.0 = 168

Hydrogen: 14 x 1.00 = 14

Sodium: 1 x 22.0 = 22.0

Nitrogen: 3 x 14.00 = 42

Oxygen: 3 x 15.99 = 47.97

Sulphur: 1 x 32.0 = 32.0

Total Methyl orange molar mass = 327,33 g/mol

Percentage mass of Nitrogen = mass of nitrogen/ mass of methyl orange x 100

42/327.33 x100

= 12.8%
