Answer:
the percent calcium in calcium chloride is 36.11%.
Explanation:
To calculate the percent calcium in calcium chloride, we need to determine the molar mass of calcium chloride and the molar mass of calcium.
1. Find the molar mass of calcium chloride (CaCl2).
- The molar mass of calcium (Ca) is 40.08 g/mol.
- The molar mass of chlorine (Cl) is 35.45 g/mol.
- Multiply the molar mass of calcium by its subscript in the formula (1) and the molar mass of chlorine by its subscript in the formula (2): (1 x 40.08 g/mol) + (2 x 35.45 g/mol) = 110.98 g/mol.
2. Determine the molar mass of calcium.
- The molar mass of calcium is 40.08 g/mol.
3. Calculate the percent calcium in calcium chloride.
- Divide the molar mass of calcium by the molar mass of calcium chloride and multiply by 100 to get the percentage: (40.08 g/mol / 110.98 g/mol) x 100 = 36.11%.
Therefore, the percent calcium in calcium chloride is 36.11%.
