A sample of wood occupies a space of 200 mL and has a mass of 75 g. What is the density?

0.375 g/mL

Explanation:

Given data:

Volume occupy by wood = 200 mL

Mass of wood = 75 g

Density of wood = ?

Solution:

Formula:

d = m/v

by putting values,

d = 75 g/ 200 mL

d = 0.375 g/mL

Nitrogen

Explanation:

Nitrogen has 5 Valence Electrons.

And its atomic mass is also less than Bismuth.

There are other elements in the 5th row but this one has the lowest atomic mass compared to the others.
