What is the molarity of 0.96 g MgCl2 in 0.500 L of solution?

Answer 1

The molar mass of MgCl2 is 95.21 g. Therefore 0.96 grams is 0.01008 mol of the substance. So the molarity of the solution is 5.04 x 10-3 M.

Answer 2

To find the molarity, first calculate the moles of MgCl2 using its molar mass. Molar mass of MgCl2 = 95.21 g/mol Moles of MgCl2 = 0.96 g / 95.21 g/mol = 0.0101 mol Then, divide the moles by the volume in liters to find molarity: Molarity = 0.0101 mol / 0.500 L = 0.0202 M.
