Question

Calculate the mass percent by volume of 34.1 g of glucose

(C.H120., MM = 180.2 g/mol) in
325 mL of solution.

Answer 1

10.5%

Step-by-step explanation:

The equation used to calculate mass percent by volume is:

Mass Solute (g)
Mass/Volume % = ----------------------------------- x 100%
Volume Solution (mL)

In this case, the solute is the glucose. You can plug the given values into the equation and solve.

34.1 g C₆H₁₂O₆
Mass/Volume % = ------------------------------- x 100%
325 mL soln

Mass/Volume % = 0.105 x 100%

Mass/Volume % = 10.5%
