To determine the molar mass of CaSiO3 (calcium silicate), we need to calculate the sum of the atomic masses of all the elements in the compound.
The atomic masses of the elements are as follows:
- Calcium (Ca) = 40.08 g/mol
- Silicon (Si) = 28.09 g/mol
- Oxygen (O) = 16.00 g/mol
To calculate the molar mass of CaSiO3, we multiply the atomic masses by the respective subscripts and sum them up:
Molar mass of CaSiO3 = (1 × Ca) + (1 × Si) + (3 × O) = (1 × 40.08 g/mol) + (1 × 28.09 g/mol) + (3 × 16.00 g/mol) = 40.08 g/mol + 28.09 g/mol + 48.00 g/mol = 116.17 g/mol
Therefore, the molar mass of CaSiO3 is approximately 116.17 g/mol.
