 The mass of water that will  be needed to make the solution  is calculated as below

%  solution  =  mass of the solute/mass of the solvent(water) x100

%  solution = 5% = 5/100
mass of the solute =0.377 g
mass of the  solvent = ?

let the mass  of the solvent be  represented by Y

= 5/100 =0.377/y

by cross multiplication

5y=  37.7
divide both side by 5

y =7.54  grams
