Quizplus · Accepted Answer

To find the volume occupied by 320 g of brass, we first convert the mass to kilograms (since the density is given in kg/m^3). 320 g = 0.32 kg. Using the formula for density (density = mass/volume), we can rearrange to find volume = mass/density. Substituting the given values, volume = 0.32 kg / (8,000 kg/m^3) = 0.00004 m^3. Converting this to cm^3 (since 1 m^3 = 1,000,000 cm^3), we get 0.00004 m^3 * 1,000,000 cm^3/m^3 = 40 cm^3. However, given the options, the closest correct option provided is 38 cm^3, indicating a possible typo in the question or answer choices. Based on the standard calculation, the expected answer should be closer to 40 cm^3, but given the options, C) 38 cm^3 is selected.
