What is the mole fraction of HCl?
Hence, the mole fraction of HCl is 0.1 and mole fraction of water is 0.9 in a 20\% w/w aqueous HCl solution.
What is the molarity of 36\% HCl?
11.65

What is the molarity of a concentrated hydrochloric acid solution that is 36\% by mass and has a density of 1.18 g mL?
molarity≡1.18⋅g⋅mL−1×1⋅mL36.46⋅g⋅mol−1×36\%1⋅mL×10−3⋅L⋅mL−1=11.65⋅mol⋅L−1 …
What is meant by 36\% HCl?
A mass percent of 36\% means that 36 grams of hydrochloric acid, HCl H C l , is dissolved in every 100 grams of the solution.
What is the molar mass of HCl?
36.458 g/mol
Hydrochloric acid/Molar mass
What is the molarity of 38 HCl?
Molarity = 12.61 Molar and 7.96 ml of HCl(38\%) needed for 1.0 Liter of 0.10 Molar HCl(aq).
How many moles are in 37 HCl?
Therefore, we can say that 1 liter of Hydrochloric acid contains 12.178 moles of HCl or in other words molarity of 37\% (w/w) Hydrochloric acid is equal to 12.178 M.
How do you find the molarity of 37 HCl?
12M (37\% HCL) = 12 moles/L = 12 x 36.5 = 438 g/L = 438 mg/ml. 0.1 M x 36.5 = 3.65 g/L = 3650 mg.
What is the volume of concentrated HCl of 36 HCl by mass?
Volume of conc. acid=0.102⋅mol11.64⋅mol⋅L−1=0.00874⋅L , i.e. 8.70⋅mL .
What is the mass of HCl?
How do you find the molarity of 35 HCl?
To obtain the Molarity of Concentrated acid, this simple formula can be applied: \%purity*specific gravity*10 divided by Molar mass of the acid.
How do you calculate the mass of HCl?
To convert volume to mass, we need the density of the solution. The specific gravity (density relative to the density of water) of hydrochloric acid solution is 1.18 g/mL. If 13.7 mL of hydrochloric acid solution is taken, then [13.7 mL x (1.18 g/mL) = 16.2 g is the mass of the hydrochloric acid solution.
