To calculate the percentage by weight of calcium in Ca(OCl)2, we need to find the molar mass of Ca(OCl)2 and the molar mass of calcium.
Molar mass of Ca(OCl)2:
Ca = 40 (atomic mass of calcium)
O = 16 (atomic mass of oxygen)
Cl = 35.5 (atomic mass of chlorine)
Ca(OCl)2 = (1 * 40) + (2 * (16 + 35.5)) = 40 + 2 * 51.5 = 143
Molar mass of calcium = 40
Percentage by weight of calcium in Ca(OCl)2 can be calculated using the equation:
(Atomic mass of calcium / Molar mass of Ca(OCl)2) * 100
Plugging in the values:
(40 / 143) * 100 ≈ 27.97%
Therefore, the percentage by weight of calcium in Ca(OCl)2 is approximately 27.97%.
What is the percentage by weight of calcium in CA(OCL)2? [CA=40,Cl=35•5,O=16].
