What is the molarity of 48.6 g of magnesium ions in 2LH2O?

Answer 1

To find the molarity of magnesium ions in 2 L of water, first, calculate the number of moles of magnesium (Mg) from the given mass. The molar mass of magnesium is approximately 24.31 g/mol. Therefore, the number of moles in 48.6 g is 48.6 g / 24.31 g/mol ≈ 2.00 moles. Since molarity (M) is defined as moles of solute per liter of solution, the molarity of magnesium ions in 2 L of water is 2.00 moles / 2 L = 1.00 M.
