I think the best answer for this question is the third option. Electrons form a cloud around the nucleus. According to modern physics, electrons are in constant motion around the nucleus and protons. Additionally, electrons, protons and neutrons are considered as hard particles.
Answer:
0.257M HNO3
Explanation:
The reaction of HNO3 with Ba(OH)2 is:
2 HNO₃ + Ba(OH)₂ → 2 H₂O + Ba(NO₃)₂
That means 2 moles of HNO3 reacts with 1 mole of Ba(OH)2.
51,3mL of 0.250M Ba(OH)2 are:
0.0513L ₓ (0.250mol / L) = 0.0128moles
Moles of HNO3 are:
0.0128moles Ba(OH)2 ₓ (2 mol HNO3 / 1 mol Ba(OH)2) = 0.0257mol HNO3
As these moles are in 0.100L:
0.0257mol HNO3 / 0.100L = <em>0.257M HNO3</em>

I hope it helps!
There is a co2 contotution
U gotta know the atom numbers of each all 161/100=m/…. Well we have to know the capacity of CCl4 to do this question how many moles do we have ? Let’s say 1 okay then m will be 1.61 After finding it we are gonna add 79.35g
79.35+1.61=80.96 hope that it helped ;)
