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
