Question

How many grams of copper (II) fluoride (CuF2) are needed to make 9.66 liters of a 2.73 M

solution?

Answer 1

Mass of Copper (II) fluoride needed = = 2677.87 g

Further explanation

Given

9.66 L of 2.73 M Copper (II) fluoride

Required

Mass

Solution

Molarity : mol solutes per liters of solution

M = n : V

n = mol solute

V = volume of solution

mol Copper (II) fluoride :

= M x V

= 2.73 M x 9.66 L

= 26.3718 mol

Mass Copper (II) fluoride :

= mol x MW CuF₂

= 26.3718 mol x 101,543 g/mol

= 2677.87 g
