Question

1. a radiation technologist is asked to find out how much 25 cc of lead weighs. if lead has a density of 11.34 g/cm³, determine the weight of this

Explanation:

Step1: Recall the density formula

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

Step2: Substitute the given values

Given \(d = 11.34\space g/cm^{3}\) and \(V=25\space cm^{3}\) (since \(1\space cc = 1\space cm^{3}\)). Then \(m=11.34\times25\).
