Final answer:
The volume of 73g of Osmium, with a density of 22.5g/cm³, is calculated using the formula volume = mass / density. The result is 3.24 cm³, which corresponds to answer choice (A).
Step-by-step explanation:
To calculate the volume occupied by a substance given its mass and density, you use the formula Volume = Mass / Density. For Osmium, with a mass of 73g and a density of 22.5g/cm³, the volume is calculated as follows:
Volume = 73g / 22.5g/cm³ = 3.244444... cm³
Rounding to two decimal places, the volume occupied by 73g of Osmium is 3.24 cm³.
Therefore, the correct answer from the options given is (A) 3.24 cm³.
