What is the mass percent of a solution of 7.6 g of sucrose in 83.4 g of water?

To calculate the mass percent of a solution, you need to follow these steps:

1. First, you need to find the total mass of the solution. This is done by adding the mass of the solute (sucrose) to the mass of the solvent (water). In this case, 7.6 g (sucrose) + 83.4 g (water) = 91 g (total mass of the solution).

2. Next, you calculate the mass percent of the solute (sucrose). The formula for mass percent is: (mass of solute / total mass of solution) * 100%.

3. Substituting the given values into the formula gives: (7.6 g / 91 g) * 100% = 8.35%.

So, the mass percent of the sucrose in the solution is approximately 8.35%.
