Answer:

7C+5H+3NO+S

7(12.01) + 5(1.008)+(14.01)+3(16)+(16)

(multiply each ex. 7 × 12.01 = 84.07 gamit kalang Po calculator )

84.07 + 5.04 + 14.01 + 48 + 16 [add mo lahat (addition)]

=151.12 g/mol

(ito Po Yung answer)

% (C) 5.04 ÷ 151.12 × 100 = 55.64%

% (H) 5.04 ÷ 151.12 × 100 = 3.34%

% (N) 14.01 ÷ 151.12 × 100 = 9.28%

% (O) 48 ÷ 151.12 × 100 = 31.77%

% (S) 16 ÷ 151.12 × 100 = 10.59%
