Question

What volume of 18.0 M sulfuric acid must be used to prepare 15.5 L of 0.195 M sulfuric acid solution? O a. 168 ml O b.0.336 L O C. 168 L O d. 226 mL 923 m

Answer 1

Dear student,

Aus- ratio Molarity may be define as the of number of molers per must volume. Molarity = moles moles Volume Here, it is given that the concentration of one of H₂ Soy is higher as compare to other H₂ soy solution. Molarity of concentrated H₂SO4 = 18M Molarity of diluted H₂ Soy = 0.195M. volume g dilute H₂ Soy = 15.5L let the volume of concentrates H₂ Boy be v liter. Moles of dilute H₂ Soy solution can be Calculated as follow, = No. g moles Molarity volume of solution in liter

No. g moles = Molarity & volume of sole in liter = 0.195 mol x 15.5X = 3.0225 mol o. Moles of dilute H₂ Soy solution = 3.0225 mol, This can be prepared by dilution of concentrated H2 soy solution to v liter Now, Molarity = No. g moles volume of solution in liter Noig moles & volume of solution - in liter Molarity & V = 3.022 5 mol 18 mot

V = 0.168 L W = 168mt al = 1000 mi?

Hence option A. 168 ml is correct answer.
