You must know the density of the substance. Assume 2g/cm^3
V = 90g/Density = 90/2 = 45 cm^3.
V = 90g/Density = 90/2 = 45 cm^3.
The formula for density is:
Density = Mass / Volume
Rearranging the formula, we get:
Volume = Mass / Density
Since we have the mass (90 grams), we need to know the density for a specific substance. The density can vary depending on the material. For example, the density of water is approximately 1 gram per milliliter (g/mL). If we assume that the substance in question has a density of 1 g/mL, we can calculate the volume as follows:
Volume = 90 g / 1 g/mL = 90 mL
Therefore, if the substance's density is 1 g/mL, 90 grams would occupy a volume of 90 milliliters. However, keep in mind that the density may vary for different substances, so it is important to know the density of the specific material you are working with to calculate the volume accurately.
