Calculate the percentage composition of oxygen in calcium trioxocarbonate(IV) [Ca=40, C=12, O=16]

Calculate the percentage composition of oxygen in calcium trioxocarbonate(IV) [Ca=40, C=12, O=16]

  • A.
    16
  • B.
    48
  • C.
    40
  • D.
    12
Correct Answer: Option B
Explanation

Calcium trioxocarbonate (IV) = CaCO(_3)

  Percentage of Oxygen = (frac{text{Molar mass of 3O}}{text{Molar mass of} CaCO_3}) × 100%

  Percentage of Oxygen = (frac{(3 times 16)}{(40 + 12 + 48)})  x 100%

  Percentage of Oxygen = (frac{48}{100}) x 100%

  Percentage of Oxygen = 48%
