Glucose is a sugar that is found abundantly in nature. What is the percent by mass of a solution made by dissolving 163g of glucose in 755 gram of water? Do you need to know the formula of glucose? why Or why not?

Answer 1

The formula of glucose is not needed to solve this problem.

To find the percent by mass of a solution, we need to divide the mass of the solute (glucose) by the mass of the solution (glucose + water) and multiply by 100.

Percent by mass = (mass of solute / mass of solution) x 100

In this case, the mass of solute (glucose) is 163g, and the mass of solution (glucose + water) is 163g + 755g = 918g.

Percent by mass = (163g / 918g) x 100 = 17.75%

Therefore, the percent by mass of the solution is 17.75%.
