Answer:
The calculated solution density is lower than the actual density.
Step-by-step explanation:
If the student spilled some of the solutions before measuring the mass, the calculated mass of the solution will be lower than the actual mass of the solution. This means that the calculated density of the solution will be higher than the actual density of the solution since the calculated density is the mass of the solution divided by the measured volume of the solution. In other words, the calculated density will be overestimated due to the lower measured mass of the spilled solution, leading to a potential error in the density measurement.
Assuming that the spilled solution was of the same density as the remaining solution, the effect of spilling some of the solutions before measuring the mass would be that the calculated solution density would be lower than the actual density. This is because the calculated density is based on the measured mass and the remaining volume, which is now smaller than the actual volume due to the spilled solution. As a result, the calculated density would be lower than the actual density.
