    Density
In summary, we have a substance with a density of 2.40 g mL-1 and a weight of 100g. To find its volume in mL, we divide 100 by 2.4 and get 41.67 mL.

100/2.4= 0.024 mL ! i don't know if its right :(

It's set up correctly but how do get that small of a number by dividing 100 by less than three?

Oh, I don't know. 100/3=33.33333 and 100/2=50. Seems like 100/2.4 should be something between 33 and 50...

1. What is the significance of the volume of 100g substance being 41.7 mL?

The volume of 100g substance being 41.7 mL indicates the density of the substance. Density is a measure of how much mass is contained in a certain volume. In this case, the substance has a density of 0.417 g/mL.

2. How is the volume of 100g substance measured?

The volume of 100g substance can be measured using various methods such as displacement, graduated cylinders, or volumetric flasks. These methods involve accurately measuring the volume of liquid displaced by the substance, or the volume of the substance itself.

3. Can the volume of 100g substance change?

Yes, the volume of 100g substance can change depending on external factors such as temperature and pressure. This change in volume is known as thermal expansion or contraction.

4. Why is the volume of 100g substance important in scientific research?

The volume of 100g substance is important in scientific research as it can help determine the physical properties of a substance, such as density and molar mass. It also aids in calculations and experiments involving the substance.

5. How does the volume of 100g substance relate to its weight?

The volume of 100g substance and its weight are related through the substance's density. The density can be used to convert between volume and weight measurements, allowing for accurate calculations and comparisons between different substances.
