Answer:
Carbon or the symbol C has a mass percentage of 42.880% while Oxygen or symbol O has a mass percentage of 57.120%
C = 42.86%
O = 57.14%
Explanation:
Percentage composition = (mass/molar mass) x 100
CO = Molar Mass 28g/mol
C = 12g/mol
O = 16g/mol
C = 12/28 x 100 = 42.86%
O = 16/28 x 100 = 57.14%
