Question

Researchers have discovered that a moon rock brought back by the Apollo astronauts has a mass of 5.671 kg and a volume of 1,698 cm3. What is the density of the rock? Remember to use the correct number of significant digits in your answer. 3.3398 g/cm3 3.340 g/cm3 0.2994 g/cm3 3.3398 x 10-3 g/cm3

Answer 1

Answer:The density of the moon rock is $3.3398 g/cm^3$.

Explanation:

Mass of the  moon rock = 5.761 kg = 5671 g

(1 kg = 1000 g)

Volume of the moon rock = $1,698 cm^3$

$Density=\frac{Mass}{Volume}=\frac{5761 g}{1,698 cm^3}=3.3398 g/cm^3$

The density of the moon rock is $3.3398 g/cm^3$.

Answer 2

I believe the answer is 3.340 g/cm3 .
