A solution labelled 10% glucose in water by mass is made from what?
A10 g glucose in 110 g water
B10 g glucose in 90 g water
C10 g glucose in 100 g water
D10 g glucose in 1 L of water
Answer & Solution
Correct answer: B. 10 g glucose in 90 g water
Mass percent uses total solution mass, so 10 g glucose plus 90 g water gives 100 g of solution.
