How many grams (of mass m ) of glucose are in 355 mL of a 5.50 % (m/v) glucose solution?

Sagot :

Solution = solute + solvent (generally water)

% (m/v): mass of solute diluted in 100 mL of solution

We have here 355 mL of 5.50 %(m/v) solution.

To find the mass of glucose, we proceed like this:

5.50 %(m/v): 5.50 g of glucose ----- 100 mL of solution

So,

5.50 g of glucose ------- 100 mL of solution

x -------- 355 mL of solution

x = 355 mL x 5.50 g / 100 mL

x = 19.5 g of glucose = answer
