Hello There!!
Given,
Mass= 20.0g
Volume= 4.0mL
To Find,
Density of substance
We Know,
[tex]\text{Density} = \frac {\text{Mass}}{ \text{Volume}}[/tex]
Inserting The Values
[tex] \text{Density} = \frac{20.0 \text{ \: g}}{4.0 \: \text{mL}} \\ \\ \text{Density} = \frac{ \cancel{20.0}\text{ \: g}}{ \cancel{4.0} \: \text{mL}} \\ \\ \text{Density} = 5.0 \: \text{g/mL}[/tex]
[tex]\therefore \text{Option B}= 5.0 \: \text{g/mL is the correct answer}[/tex]
Hope this helps
