What volume of hydrogen gas at and pressure will be consumed in obtaining of elemental boron (atomic mass from the reduction of boron trichloride with hydrogen :

A

`67.2 L`

B

`44.8 L`

C

`22.4 L`

D

`89.6 L`

Text Solution

Verified by Experts

The correct Answer is:
A
No. moles of boron `= (21.6)/(10.8) = 2`
`2BCl_(3) + 3H_(2) rarr 6HCl + 2B`
For the formation of `2` moles of B, volume of `H_(2)` required `= 3 "mol" = 3 xx 22.4 = 67.2 L`
