1 cubis feet = 28.3 Lit or 28.3 kg of water
5 cubic feet = 5 X 28.3 = 141.5 lit of water having 2M of HCl
HCl moleculer weight + 36.46
Molarity = W/M.WtX 1/Lit
2 = W/ 36.46 X 1/141.5
a). Weight of HCl = 2 X 36.46 X141.5 = 10318.18gr
b). 141.5 lit of water need
c). mole fraction of HCl
HCL moles = 10318.18/36.46 = 282.99 mole
H2O moles = 141500/18 = 7861.11 moles
mole fraction of HCl = 282.99/ 282.99+7861.11= 0.035

- What is the molarity of a solution in which 0.051 grams of sodium thiosulfate is prepared in a solution having a total volume of 200.00 mL Neutralization is the reaction between an acid and a base, producing a salt and neutralized base. For example, hydrochloric acid and sodium hydroxide form sodium chloride and water: HCl(aq)+ NaOH(aq) H2O0+NaCl(aq) a. Using the previous reaction, if 35 ml of 0.1 M NaOH will neutralize 10 mL of HCl, what is the concentration...
