The concentration of the HCl solution is 0.047 M.
Explanation:
Data given about acid and base:
volume of acid Vacid = 46.9 ml
molarity of acid =?
volume of the base (NaOH) = 16.4 ml
molarity of the base = 0.135 M
To know the concentration of the acid in this reaction, the formula used in titration is used. It is
Macid X Vacid = Mbase X Vbase
the formula is rewritten as:
Macid = 
putting the values in the equation:
Macid = 
= 0.047 M
the concentration of the acid i.e HCl in the solution is of 0.047 M.
Adding perchloric acid to water would cause it's conductivity to increase.
hydrogen (H2),and oxygen (O2),, that is the answer
You would find the atomic weight of phosphorus and multiply that 2.3 and get 71.23.
Answer: melting, freezing, sublimation, deposition, condensation, and vaporization
