D)241 g

Question

Quizplus · Accepted Answer

The mass of magnesium sulfate can be calculated using the formula: mass = molarity (M) × volume (L) × molar mass (g/mol). The molar mass of magnesium sulfate (MgSO4) is approximately 120.4 g/mol. The volume needs to be converted to liters (0.400 L). So, the calculation is: 0.800 M × 0.400 L × 120.4 g/mol = 38.5 g.
