How many grams of sucrose are needed to make 875ML of a 40% (w/v) sucrose solution
To answer this question, we need to use the formula:
% (w/v) = (mass of solute / volume of solution) x 100
We rearrange this formula to solve for the mass of solute:
mass of solute = (% w/v / 100) x volume of solution
Plugging in the values given in the question, we get:
mass of sucrose = (40 / 100) x 875ML
mass of sucrose = 350 grams
Therefore, 350 grams of sucrose are needed to make 875ML of a 40% (w/v) sucrose solution.
