determine the molar mass of the compound CuSO4½H2O
To determine the molar mass of the compound CuSO4½H2O, we need to calculate the molar mass of each component separately and then add them up.
1. Copper (Cu) has a molar mass of approximately 63.55 g/mol.
2. Sulfur (S) has a molar mass of approximately 32.06 g/mol.
3. Oxygen (O) has a molar mass of approximately 16.00 g/mol.
4. Hydrogen (H) has a molar mass of approximately 1.01 g/mol.
5. Water (H2O) has a molar mass of:
- 2 hydrogen atoms * 1.01 g/mol = 2.02 g/mol
- 1 oxygen atom * 16.00 g/mol = 16.00 g/mol
Total molar mass of H2O = 18.02 g/mol.
Now, let's add up the molar masses of each component in the compound CuSO4½H2O:
Cu: 1 * 63.55 g/mol = 63.55 g/mol
S: 1 * 32.06 g/mol = 32.06 g/mol
O: 4 * 16.00 g/mol = 64.00 g/mol
H2O: 1 * 18.02 g/mol = 18.02 g/mol
Add them up:
63.55 + 32.06 + 64.00 + 18.02 = 177.63 g/mol
Therefore, the molar mass of CuSO4½H2O is approximately 177.63 g/mol.
