Question

A student massed an unknown sample and found it to be 23.5g. The volume of the sample is 2.00mL. Calculate the density

Answer 1

Answer:

The density of the sample is 11.8 g/mL.

Explanation:

We are given an unknown sample with a mass of 23.5 g and a volume of 2.00 mL and we want to determine its density.

Recall that density is given by:

$\displaystyle \rho = \frac{m}{V}$

Where ρ is the density, m is the mass, and V is the volume.

Substitute 23.5 g for m and 2.00 mL for V and evaluate:

$\displaystyle \begin{aligned} \rho & = \frac{m}{V} \\ \\ & = \frac{(23.5\text{ g})}{(2.00 \text{ mL})}\\ \\ & = 11.8 \text{ g/mL}\end{aligned}$

Hence, the density of the sample is 11.8 g/mL.

Answer 2

Answer:

mass=23.5g

volume=2.88ml

Explanation:

But density= mass/volume

23.5/2.88

=8.15kgm^-3
