Question

Molarity of liquid HCl will be, if density of solution is 1.17 gm/cc
(a) 36.5
(b) 32.05
(c) 18.25
(d) 42.10

Answer 1

YOUR ANSWER IS :

Given:Density of HCl=1.17g/cm³

Molarity=(density/molar mass)x1000 moles per liter

molar mass of HCl=[1+35.5]=36.5g/mol

Molarity=(1.17/36.5)x1000               =32.05M

∴Molarity of liquid HCl with density equal to 1.17 g/cc is 32.05
