Question

What would occupy a larger volume: 100 g of Substance A or 100 g of Substance B?​

Answer 1

100 g of a salt solution would typically occupy a larger volume than 100 g of a metal bar.

How to determine occupancy?

To determine which of the two substances - a salt solution or a metal bar - would occupy a larger volume when each weighs 100 grams, consider the density of each substance.

Salt Solution: The density of a salt solution depends on the concentration of salt in the water. A typical saltwater solution might have a density slightly higher than that of water (1 g/cm³), but it usually doesn't exceed 1.2 g/cm³.

Metal Bar: The density of the metal bar depends on the type of metal. Metals generally have higher densities compared to water. For example, iron has a density of about 7.87 g/cm³, aluminum about 2.7 g/cm³, and lead about 11.34 g/cm³.

To compare the volumes, use the formula:

`\[ \text{Volume} = \frac{\text{Mass}}{\text{Density}} \]`

Given that the mass (100 g) is the same for both substances, the substance with the lower density will occupy a larger volume. In general, a salt solution would have a lower density than most metals, so 100 g of a salt solution would typically occupy a larger volume than 100 g of a metal bar.
