Question

Find the volume of an object that has a density of 10.2g/mL and a mass of 30.0g.Find .

Answer 1

V ≈ 2.94 mL

Step-by-step explanation:

To find the volume of the object, you can use the formula for density:

`\boxed{\left\begin{array}{ccc}\text{\underline{Density:}}\\\\ \rho=(M)/(V)\\\\\text{Where:}\\\bullet \text{ $\rho$ is the density}\\\bullet \text{ $M$ is the mass}\\\bullet \text{ $V$ is the volume}\end{array}\right}`

In this case, you want to find the volume (V) of an object that has a density (ρ) of 10.2 g/mL and a mass (M) of 30.0 g. You can rearrange the formula to solve for 'V':

`\rho=(M)/(V) \longrightarrow \boxed{V=(M)/(\rho)}`

Substitute in the given values:

`\Longrightarrow V=(M)/(\rho)\\\\\\\\\longrightarrow V=(30.0 \ g)/(10.2 \ g/mL)\\\\\\\\\therefore \boxed{\boxed{V \approx 2.94 \ mL}}`

So, the volume of the object is approximately 2.94 mL.
