Final answer:
The molar mass of Calcium Nitride (Ca3N2) is found by summing the product of each element's atomic mass and its quantity within a single formula unit, resulting in a molar mass of 148.26 g/mol.
Step-by-step explanation:
The molar mass of Calcium Nitride (Ca3N2) is calculated by finding the sum of the molar masses of all the atoms in one formula unit of the compound. You can find it by multiplying the atomic mass of calcium by the number of calcium atoms in the formula, and the atomic mass of nitrogen by the number of nitrogen atoms, then adding those together. As Calcium has an atomic mass of 40.08 g/mol and Nitrogen has an atomic mass of 14.01 g/mol, we calculate:
- Calcium: 40.08 g/mol × 3 = 120.24 g/mol
- Nitrogen: 14.01 g/mol × 2 = 28.02 g/mol
Add these values together to get the total molar mass of Ca3N2:
120.24 g/mol + 28.02 g/mol = 148.26 g/mol
This represents the mass in grams of one mole of Calcium Nitride.
