Final answer:
The mass of the sample of Chromium is 17.256 grams.
Step-by-step explanation:
To determine the mass of a sample of Chromium, you need to use the formula: mass = volume x density. Given that the volume is 2.4 cm³ and the density is 7.19 g/cm³, you can calculate the mass as follows:
mass = 2.4 cm³ x 7.19 g/cm³ = 17.256 g
Therefore, the mass of the sample of Chromium is 17.256 grams.
