Answer:
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%
