mrs. branigan gives you a rock with a volume of 15cm3 and a mass of 45 g. what is its density?
30 g/cm3
3 g/cm3
5 g/cm3
0.3 g/cm3

Explanation:

Step1: Recall the formula for density

Density formula is \(
ho=\frac{m}{V}\), where \(m\) is mass and \(V\) is volume.

Step2: Substitute the given values

Given \(m = 45\space g\) and \(V=15\space cm^{3}\). Then \(
ho=\frac{45}{15}\).

Step3: Calculate the density

\(\frac{45}{15}=3\space g/cm^{3}\)

Answer:

3 g/cm3
