Given what we know, we can confirm that John Dalton was the first person to show strong empirical evidence for the existence of atoms.
<h3>Who was John Dalton?</h3>
- He was a renowned scientist with knowledge in many fields.
- He was known to be a chemist, meteorologist, and physicist.
- He proposed the atomic theory and carried out experiments to provide supporting evidence.
Therefore, given his proposal of the atomic theory and the experiments he carried out to provide evidence to support his claims, we can confirm that John Dalton was the first person to show strong empirical evidence for the existence of atoms.

Answer:
86 mL
Explanation:
First find the moles of Pb (NO3)2
n=cv
where
c ( concentration)= 0.210 M
v ( volume in L) =0.05
n= 0.210 × 0.05
n= 0.0105
Using the mole ratio, we can find the moles of KCl by multiplying by 2
n (KCl) =0.0105 ×2
=0.021
v (KCl)= n/ c
= 0.021/ 0.244
=0.08606557377
=0.086 L
= 86 mL
