Question

What is the density of the solid object that is weighed and submerged in the water

Short answer

The solid item that is submerged in water has a density of$9.8g/mL$

Step-by-step solution

Introduction 

The given is the weight of a solid object that is submerged in the water

The objective is to find the density of the solid object submerged in the water

Step 1

Any substance's density is defined as the ratio of mass to volume. As a result, a substance's density is an inherent attribute.

The solid object of $8.24g$ is submerged in the graded cylinder containing water in this problem. $18.5mL$ is the initial volume of water in the cylinder. After immersing an object, the volume of water is $23.1mL$.

A given object's mass is $8.24g$

$$\begin{gathered} Volumeincreasedbysubmerging=Finalvolume-Initialvolume \\ =23.1-18.5 \\ =4.6mL \end{gathered}$$

.Thus, the volume of the object is$4.6mL$

Step 2

The object's mass is $8.24g$with three significant figures, whereas its volume is $4.6mL$with two significant numbers. When performing this computation, we must take into account significant figure calculation criteria.

Density of solid object $=\frac{\text{mass in}\mathrm{g}}{\text{volume in}\mathrm{mL}}$

$$\begin{gathered} =\frac{8.24g}{4.6mL} \\ =1.79gmL \end{gathered}$$

The denominator, on the other hand, has two significant figures, hence the answer should also have two significant figures.

As a result, the answer is The solid object's density.$1.8g/mL$

The solid item submerged in water has a density of

$1.8g/mL$
