What is the molar mass of Ca(NO3)2? You can round molar masses of individual elements to lowest whole numbers, and then calculate the molar mass of the compound. 1 point164 g/mol102 g/mol82 g/mol150 g/mol
Solution
To calculate the molar mass of Ca(NO3)2, we need to know the molar masses of Calcium (Ca), Nitrogen (N), and Oxygen (O).
- The molar mass of Calcium (Ca) is approximately 40 g/mol.
- The molar mass of Nitrogen (N) is approximately 14 g/mol.
- The molar mass of Oxygen (O) is approximately 16 g/mol.
In the formula Ca(NO3)2, there is one atom of Calcium, two atoms of Nitrogen, and six atoms of Oxygen.
So, the molar mass of Ca(NO3)2 is calculated as follows:
(1 x 40 g/mol for Ca) + (2 x 14 g/mol for N) + (6 x 16 g/mol for O) = 40 g/mol + 28 g/mol + 96 g/mol = 164 g/mol
So, the molar mass of Ca(NO3)2 is 164 g/mol.
