Question
What is the mass of 1 mole of MgSO4?A.88.4 gB.216.7 gC.120.4 gD.72.4 g
Solution
To find the molar mass of MgSO4, we need to add up the molar masses of each individual element in the compound.
- The molar mass of Magnesium (Mg) is approximately 24.3 g/mol.
- The molar mass of Sulfur (S) is approximately 32.1 g/mol.
- The molar mass of Oxygen (O) is approximately 16.0 g/mol. However, since there are 4 oxygen atoms in MgSO4, we multiply 16.0 g/mol by 4 to get 64.0 g/mol.
Now, we add up these molar masses:
24.3 g/mol (Mg) + 32.1 g/mol (S) + 64.0 g/mol (4O) = 120.4 g/mol
So, the molar mass of MgSO4 is 120.4 g/mol. Therefore, the mass of 1 mole of MgSO4 is 120.4 g. The correct answer is C. 120.4 g.
