What volume of HCI solution of density 1...

What volume of `HCI` solution of density `1.2g/cm^3` and containing `36.5%` by mass `HCI`, must be allowed to react wtih zinc `(Zn)` in order to liberate `4.0 g` of hydrogen ?

A

333.33 mL

B

500 mL

C

614.66 mL

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A
`Zn + 2HCl rarr ZnCl_(2) + H_(2)`, Moles of `H_(2)` evolved = 2
`:.` moles of HCl required = 4 `:. (v xx 1.2 xx 0.365)/(36.5) = 4, V = 333.33 mL`
