Question

An element in its solid phase has mass density 1750 kg/m3

and number density 4.3

Short answer

The solution deals with the solid phase and the mass density of matter.

Step-by-step solution

Description on the mass density

It deals with the density and the mass of a matter described in Physics

Description on mass, density of matter

Provided solution

$$\begin{gathered} P=\frac{m}{v} \\ v=\frac{m}{p} \\ N=\frac{M}{m} \\ M=\frac{p}{numberdensity} \\ m=(3.98\times {10}^{-26kg})=\left(\frac{1u}{1.66\times {10}^{-27kg}}\right)=24u \end{gathered}$$
