Answer 1

To find the molarity Given that 0.700 mole of Na Sin 1.65L of solution Molarity = moles of solute liters of solution 0.700 mole 1.65L = 0.42M Hence the molarity = 0.42M To find the molarity Given that 23.3 g of MgS in 747 mL of solution First find the moles of MgS moles = mass molarm ass molarmass of MgS= 56.38 g/mol 23.3g moles = 56.38g /mol = 0.413moles To find the molarity Molarity = moles of solute liters of solution 747 mL = 0.747L 0.413moles Molarity = -0747L = 0.553M Hence the molarity = 0.553M
