Final answer:
To calculate the volume occupied by a substance, divide its mass by its density. For 6.85 g of a substance with a density of 1.45302 g/cm³, the volume is approximately 4.7133 cm³.
Step-by-step explanation:
To find the volume occupied by a given mass of a substance using its density, you can use the formula:
Density = Mass / Volume
Rearranging this formula to solve for volume gives us:
Volume = Mass / Density
According to the provided data, we want to find the volume for 6.85 g of the substance. However, the density given in the question seems to contain a typo. Assuming we are working with the density of 1.45302 g/cm³ mentioned in the question, we calculate the volume like so:
Volume = 6.85 g / 1.45302 g/cm³
Volume = 4.7133 cm³ (when rounded to four significant figures)
Therefore, the volume occupied by 6.85 g of the substance is approximately 4.7133 cm³.
