Question

Total density of 3.03 x 104 g/cmº. If you had a 2.40cm sample of this matter, what would its mass be?

a) 72.72 g
b) 0.07272 g
c) 7.272 x 10^4 g
d) 72,720 g

Answer 1

The mass of a 2.40cm sample of matter with a density of 3.03 x 10⁴ g/cm³ is 7.272 x 10⁴ g, which means the correct answer is option c).

Step-by-step explanation:

To calculate the mass of a 2.40cm sample of matter with a given density, you should use the formula Mass = Density × Volume. With the density given as 3.03 x 104 g/cm3, and the volume of the sample as 2.40 cm3, you can find the mass by multiplying the two.

Mass = 3.03 x 104 g/cm3 × 2.40 cm3 = 7.272 x 104 g

Therefore, the mass of the 2.40 cm sample would be 7.272 x 104 g, which corresponds to answer choice c). It's important to remember that in problems involving measurements, the answer must be presented with the correct number of significant figures, based on the numbers provided in the question.
