Question

A 9.6 g object is placed in a graduatedcylinder displacing the volume from 10.0 mLto 13.2 mL.The volume of this object is 3.2 mL.What is its density in g/mL?Round your answer to the appropriatenumber of significant figures.[?] g/mL

Answer 1

T

Step-by-step explanation

Given that;

The mass of the object is 9.6 grams

The volume of the object is 3.2mL

Follow the steps below to find the density of the object

`\text{ Density = }\frac{\text{ mass}}{\text{ volume}}`

Substitute the given data into the formula above

Convert the volume of the object to cm^3

Recall, that 1mL is equivalent to 1cm^3

Hence, 3.2mL is 3.2 cm^3

`\begin{gathered} \text{ Density= }\frac{\text{ 9.6}}{\text{ 3.2}} \\ \text{ Density = 3.00g/cm}^3 \end{gathered}`

Therefore, the density of the object is 3.00 g/mL
