Answer / k.srinivas

According to this formula

Con(mL) =(M.Wt of Hcl * 100)/ (Specific Gravity of Hcl*
Purity of Hcl)

= 36.5 * 100 / 1.18 * 36 = 85.9mL

Answer / kizar ahamed

we should consider the density of the solution :

density= M/V
V=M/D=36.5/1.18=30.93 if purity is 100% but in the HCL ,
purity is 36% only , so

Required volume to prepare 1N solution =30.93*100/36=85ml

Answer / alpesh patel

Normality of Con. HCl =(Purity of Hcl * 10 * specific
gravity of HCl)/ Eq. wt. of HCl

Where 10 is multiplied to convert in normal soln.(1000 mL)

= (36 * 10 * 1.18)/36.5 = 11.64 N.(N1)

Now,N1V1 = N2V2

v1 = (1 * 1000)/11.64
= 85.9 mL

Answer / ponnam

FIRST WE ARE FIND OUT LAB MORMALITY=(10 X ASSAY X Wt/ml)/M.W

=(10 X 1.18 X 36)/36.5 = 11.64. THEN M1V1=N2V2 SO,V1=(1X1000)/11.64 = 85.91
