Question

1 what is the identity of a sample that has a volume of 3.62 cm³ and a mass of 28.5 g?
oa. lead
ob. iron
oc. silver
od. mercury

Explanation:

Step1: Recall the density formula

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

Step2: Substitute the given values

Given \( m = 28.5\ g \) and \( V=3.62\ cm^{3} \). Then \(
ho=\frac{28.5}{3.62}\approx7.87\ g/cm^{3} \).

Answer:

B. iron
