Explanation:
I believe that the answer is A) All Nitrogen atoms have 7 protons
D. Sodium hydroxide aka naOH
The volume occupied by the sample is 8.4 cm³
<h3>What is density?</h3>
The density is the ratio of mass of the object to its volume.
Given is the mass m =14.7 g and the density is 1.75 g/cm³, then the volume will be
ρ = m/ V
V =m /ρ
Substitute the values, we get
V = 14.7 /1.75
V = 8.4 cm³
Thus, the volume of the sample is 8.4 cm³.
