Some Basic Concepts Of Chemistry Question 134

Question: The volume of concentrated sulphuric acid which is 98% by mass (density =1.84,g,cm3 ) required to prepare 5,dm3 of 0.5moldm3 solution of sulphuric acid is

Options:

A) 272 mL

B) 68 mL

C) 136 mL

D) 204 mL

Show Answer

Answer:

Correct Answer: C

Solution:

[c] Molarity of given sulphuric acid =9898×1.84100×1000=18.4,mol,dm3

M1V1=M2V2

V1=0.5×518.4=0.136,dm3=136,mL
