The reaction of NaOH and HCl follows: NaOH +HCl ⇒NaCl + H2O.
So the ratio between the reactants is 1:1.
The moles of NaOH needed to neutralize the acid = volume of NaOH solution * concentration of NaOH solution = 0.0685 L * 0.154 M = 0.01055 mole.
Therefore 0.01055 moles of HCl is presented in the acid solution.
The concentration of HCl solution = moles of HCl/volume of HCl solution = 0.01055mole/0.025L = 0.422 M

Answer:
0.2615 g
Explanation:
Given that mass of the body = 120 lb
The conversion of lb to g is shown below as:-
1 lb = 454 g
So, 120 lb = 120*454 g = 54480 g
The substance is of the human body
So, Mass of that substance in the body of mass 54480 g is:-
<u>0.2615 g of that substance would be found in the body of a person weighing 120 lb.</u>
