Jack has a rock. The rock has a mass of 14g and a volume of 2cm3. What is the density of the rock?
A
7 mL
B
7 g/cm3
C
28 g/cm3
D
1/7 g/cm3
Explanation: 

Detailed explanation-1: -Answer and Explanation: The density of the rock is 7 g cm3.

Detailed explanation-2: -Problem 1: You have a rock with a volume of 15cm3 and a mass of 45 g. What is its density? Density is mass divided by volume, so that the density is 45 g divided by 15cm3, which is 3.0 g/cm3.

Detailed explanation-3: -density is the same as mass on volume. The mass is equal to the density on the volume. On solving, we get 6.436 g per liter.

Detailed explanation-4: -1 Answer. fruity ยท Stefan V. The answer is 2.5 g/cm3 .

Detailed explanation-5: -To calculate the density, divide the weight by the volume: 9 g / 37.5 cm3 = 0.24 g/cm3 = 240 kg/m3.
