Question

do now 3 (module 1 - lesson 3)
question 2. a sample of a metal has a density of 7.5 g/cm³ and a mass of 150 grams. what is the volume of the metal sample?
answer: cm³

Explanation:

Step1: Recall the density formula

Density formula is \(
ho=\frac{m}{V}\), where \(
ho\) is density, \( m\) is mass and \( V\) is volume. We need to solve for \( V\), so \( V = \frac{m}{
ho}\).

Step2: Substitute the given values

Given \( m = 150\space g\) and \(
ho=7.5\space g/cm^{3}\). Then \( V=\frac{150}{7.5}\).

Step3: Calculate the value

\( V = 20\space cm^{3}\)

Answer:

\(20\)
