8.40 ml. I think that is right.
Answer:
Concentration of ammonia = 3M
Explanation:
The reaction for the question is a neutralization reaction between HCl and NH₃
The chemical equation for the reaction is given as
HCl + NH₃ → NH₄CL
1 : 1 1
Volume of HCl = 18.1ml = 0.0181L
Volume of NH₃ = 5ml= 0.005L
Molar concentration of HCl=0.8M
Molar Concentration of NH₃ =?
Number of moles(n)= Molar concentration × Volume
n = C × V
n of HCL= 0.8 × 0.0181
n = 0.01448moles
Since mole ration for the reaction from the balanced equation above is 1:1,
n of NH₃ = 0.01448
molar concentration (C) of NH₃ = n/v
C of NH₃ = 0.01448/0.005
C of NH₃=2.896
C OF NH₃ =3M
