The grams of glucose are needed to prepare 400g of a 2.00%(m/m) glucose solution g is calculated as below

=% m/m =mass of the solute/mass of the solution x100

let mass of solute be represented by y

mass of solution = 400 g

% (m/m) = 2% = 2/100

grams of glucose is therefore =2/100 = y/400

by cross multiplication

100y = 800

divide both side by 100

y=

8.0 grams
