Question:
The percentage of Calcium in CaCO\(_3\) is
The percentage of Calcium in CaCO\(_3\) is
Show Hint
To calculate the percentage of an element in a compound, divide the mass of the element by the molar mass of the compound and multiply by 100.
Updated On: Apr 25, 2025
- 52%
- 48%
- 20%
- 40%
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
The molar mass of CaCO\(_3\) is 100 g/mol, and the molar mass of calcium is 40 g/mol. Thus, the percentage of calcium in CaCO\(_3\) is:
\[
\frac{40}{100} \times 100 = 40%
\]
Thus, the correct answer is 40%.
