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 = ![\frac{Mbase X Vbase}{Vacid}](https://tex.z-dn.net/?f=%5Cfrac%7BMbase%20X%20Vbase%7D%7BVacid%7D)
putting the values in the equation:
Macid = ![\frac{0.135 X 16.4}{46.9}](https://tex.z-dn.net/?f=%5Cfrac%7B0.135%20X%2016.4%7D%7B46.9%7D)
= 0.047 M
the concentration of the acid i.e HCl in the solution is of 0.047 M.
WOW, I gave you the answer, i used a periodic table, i got the mass of gold and i linked a helpful link my teacher gave me because we used it in a lab once.
Answer: The first plastic based on a synthetic polymer was invented in 1907. Plastic sticks around in the environment for ages, threatening wildlife and spreading toxins.
