The mole fraction of HCl is 0.34.
The mole fraction of HCl in 20 percent aqueous solution is 0.21.
Molarity = moles of solute/Liters of solution ( 50 ml = 0.05 Liters ) 12 M HCl = moles HCl/0.05 Liters = 0.60 moles HCl
Let A be the volume of 33% HCl and B the volume of 20% HCl Then, A + B = 5.........so, B = 5 - A And, 33A + 20B = 5 x 30.5 = 152.5 Substituting for B gives :- 33A + 20(5 - A) = 33A + 100 - 20A = 13A + 100 = 152.5 Thus, 13A = 152.5 - 100 = 52.5 : A = 52.5/13 = 4.0385 Litres (4dp) Which means that B = 5 - 4.0385 = 0.9615 Litres Mix 4.0385 Litres of 33% HCL with 0.9615 Litres of20% HCl to get 5 litres of 30.5% HCl.
50 ml
nope 50 percent.
