Question

One gram (1.00 g) of vitamin B3 (niacin) is dissolved in water to give 10.0 mL of solution. (a) What is the weight/volume percent concentration of this solution?

Answer 1

10 g % w/v

Step-by-step explanation:

Weight/volume percent concentration means the grams of solute, in 100 mL of solution.

If we have 1 g of B3 in 10mL of solution, the rule of three for the weight volume percent will be:

10mL ___ 1 g

100 mL ____ 10 g
