In this case, since the by-mass percent of a solution is a measure of the mass of the solute over the mass of the solution:

As we know the mass of the solution and the by-mass percent, we can compute the mass of glucose in the 480 g of solution:

Thus, by plugging in the data, we obtain:

Finally, since the solution is made up of glucose and water, we compute the mass of water as follows:
