To find the percent volume of a substance in a solvent, which formula is used?

The correct formula for calculating the percent volume of a substance in a solvent is derived from the relationship between the volume of the substance and the total volume being considered. In the context of solution concentration, percent volume typically describes how much volume of the solute (substance) is present in relation to the total volume of the solution.

To accurately compute the percent volume, one must consider the relative volumes, not weights. Here, by dividing the volume of the substance by the total volume of the solution and then multiplying by 100, you can determine the percentage. However, the formula presented in the answer focuses on the ratio between the grams of the substance and the volume which is a step toward understanding the relationship but does not provide the complete or correct context for volume percent.

In this case, the answer provided does not align with the standard method for calculating percent by volume. The correct approach involves obtaining the volume of the solute and the total volume of the solution. Therefore, a different formulation would be accurate for this calculation to specify the relationship between the volume of the solute and the overall total volume.

In summary, the concept of percent volume is rooted in comparing volumes directly, rather than weights. Understanding this foundational principle is key to mastering solution
