Question

You have a rock with a density of 9.00 x 10 g/L and a mass of 2 kg. What is the volume of the rock?

Option 1: 1.8 x 10^3 m³.
Option 2: 5.55 x 10^0 m³.
Option 3: 2.22 x 10 m³.
Option 4: 4.5 x 10 ml.

Answer 1

To find the volume of the rock, divide the mass by the density. Convert the density to g/cm³ and substitute the values into the formula. The correct answer is option 3: 2.22 x 10 m³.

Step-by-step explanation:

To find the volume of the rock, we can use the formula: volume = mass/density. In this case, the mass of the rock is given as 2 kg and the density is given as 9.00 x 10 g/L. We need to convert the density to g/cm³ to match the units of the mass. To do that, we multiply the density by 1000 to convert g/L to g/cm³. So, the density becomes 9.00 x 10 g/cm³. Now, we can substitute the values into the formula:

volume = 2 kg / (9.00 x 10 g/cm³)

After performing the calculation, we get the volume of the rock as 2.22 x 10 m³. Therefore, option 3: 2.22 x 10 m³ is the correct answer.
