Hi there ,
☆ To calculate the mass percentage u have the mass of each element in the compound and the mass of compound using the following formula
☆ Element mass ÷ compound mass × 100
☆ If u don't have any details use the atomic mass and molar mass as the example above
● molar mass = 12×2 + 1×5 + 14 + 16
= 59 gm
● C% = 12×2 / 59 × 100 = 40.7 %
● O% = 16 / 59 × 100 = 27.11 %
● N% = 14 / 59 × 100 = 23.72 %
