muriatic acid 11.7 M 3.5 M HCl 3.0 gallon HCl 9.66 g
Muriatic acid, an industrial grade of concentrated HCl, is used to clean masonry and cement. Its concentration is 11.7 M.
(a) Write instructions for diluting the concentrated acid to make 3.0 gallons of 3.5 M acid for routine use (1 gal = 4 qt, 1 qt = 0.946 L).
(b) How many milliliters of the muriatic acid solution contain 9.66 g of HCl?
---------------------------------------------------
(b)
HCl의 몰질량 = 36.46 g/mol
9.66 g / (36.46 g/mol) = 0.264948 mol HCl
( 참고 https://ywpop.tistory.com/7738 )
0.264948 mol HCl을 포함하는 11.7 M HCl 용액의 부피
= 0.264948 mol / (11.7 mol/L) = 0.022645 L
= 22.6 mL
