how to prepare 5 normality of h2so4 solution

Answer / ashish
H2SO4 MOLECULAR WEIGHT = 98 g/mol
H2SO4 BASISITY = 2
H2SO4 DENSITY = 1.84
SO H2SO4 NORMALITY = 98/2 = 49 g/mol
SO 49/1.84 = 26.63ml
BUT OUR H2SO4 IS 98% SO 100% = 27.17ml
SO 1000ML -------> 1N H2SOH -----> 27.17ML
1000ML -------> 5N H2SO4 -----> (?)
1000 X 5 X 27.17
------------------ = 135.85 ML
1000 X 1
SO TAKE 135.85 ML H2SO4 IN 1000ML WATER

Answer / morr
Your stock solution of Sulfuric Acid is calculated to be 35.644 N based on a density of 1.84 g/mL, a formula weight of 98.08 g/mol, and a concentration of 95% w/w.
To make a 5 N solution, slowly add 70.137 mL of your stock solution to 125 mL deionized water.
Adjust the final volume of solution to 500 mL with deionized water.
