Question

Molarity of liquid HCl will be if the density of the solution is 1.17 g/cc.

Options

• 36.5

• 32.05

• 18.25

• 42.10

Answer 1

32.05

Explanation:

Density = 1.17 g/cc ...(Given)

As d = `"Mass"/"Volume"`

Volume = 1 cc

∴ Mass = d = 1.17 g

Molarity = `("No. of moles")/("Volume in litre")`

= `(1.17 xx 1000)/(36.5 xx 1)`

= `1170/36.5`

= 32.05 M
