Question

2.76 KG of CUS 04.5H20 in 1.45 L of solution. Find molarity please give full method

Answer 1

Answer :

2.76 Kg of CuS04.5H20 in 1.45 L of solution

Molar mass of CuS04.5H20 = 159.609 g/mol

Number of moles = Mass of substance / Mass of one mole

Number of moles = 2.76 * 1000 / 159.609

                            = 17.293 moles

Molarity = no. of moles of solute / volume of solution

             = 17.293 / 1.45

             = 11.926 mol L^-1
