Final answer:
To calculate the volume of methylene chloride, divide the mass (converted to grams) by the density. For a mass of 0.391 kg and a density of 1.326 g/cm³, the calculated volume is approximately 295 cm³.
Step-by-step explanation:
The question requires us to calculate the volume of a sample of methylene chloride given its mass and density. The relationship between mass, density, and volume is given by the formula: mass = density × volume. To find the volume, we rearrange this to: volume = mass/density.
With the provided mass of the sample being 0.391 kg (or 391 grams, since 1 kg = 1000 g) and the given density of 1.326 g/cm³, we can calculate the volume as follows:
Volume = mass/density
Volume = 391 g / 1.326 g/cm³
Volume = 294.725 cm³ (approximately)
When rounded to the nearest whole number, the volume is approximately 295 cm³. Therefore, the correct option in the final answer is 295 cm³.
