Get two moles of HCl and add water until the solution is 1 L
HCl with concentration of 0.2 M (0.2 mol/L)
molar mass of HCl is 36.46 g/mol, so 0.2 M * 36.46g/mol = 7.29 g/L
so, u will need 7.29 g of HCl to make up 1 L of solution
1
combine 100 mL 6 M HCl with 500 mL H2O
85 mL of (concentrated, 38%) HCl solution contains 36.5 gram HCl, which dissolved and diluted in up to 1.0 Liter gives you an 1.0 molar solution.
0.17 Molar
dilute your HCl solution to 0.2 M HCl solution and then follow above mentioned link : http://delloyd.50megs.com/moreinfo/buffers2.html

HCl has a molar mass of 36.461 grams per mole. This means that 72.922 grams of HCl are needed per liter of water to make a solution that has a concentration of 2M.
When 100cm3 of 1.0 molar of sodium hydoxide solution at 200oc was added to 100cm3of1.0 molar of HCL solution at 200oc,then the temperature of HCL rose to 26.8oc.calculate the standard heat of neutralisation?(Given that the specific heat capacity of water is 4.2KJg-1k-1)
Molar mass of HCl = 1 + 35.5 = 36.5 Number of moles of HCl = mass / molar mass = 85.6 / 36.5 = 2.345 moles Molarity = number of moles / Volume = 2.345 / 0.385 = 6.091 M
14.5% HCL by weight, which is roughly a 4.2 molar solution
Try 1 molar sodium hydroxide NaOH solution and 1 molar hydrochloric acid solution HCl . Mix them together and you have a common salt solution NaCl in water. Not exactly sure what you wanted, but there you go.
