Answer:
5.21 % glucose
Step-by-step explanation:
Mass percent can be calculated using the following formula:
mass of solute (grams)
------------------------------------ x 100%
mass of solution (grams)
In this case, the solute is glucose. Since you were given the masses of both the solute and solution, you can substitute those values into the formula to find the mass percent.
14.54 g glucose
--------------------------- x 100% = 5.21% glucose
279 g solution
