What volume of hydrogen gas at 273 K and...

What volume of hydrogen gas at 273 K and 1 atm pressure will be consumed in obtaining 21.6 g elemental boron (atomic mass = 10.8) from the reduction of boron trichloride by 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
`2BCl_(3) + underset(3 xx 22.4 L= 67.2 L)(3H_(2)) to underset(2 xx 10.8 g= 21.6 g)(2B) + 6HCl`
