Answer:

Explanation:

Given: Mass of elemental boron = 21.6 g

           Temperature = 273 K

            Pressure = 1 atm

Solution: The balanced chemical equation for the reduction of boron dichloride is  

BCl3 +1.5H2 →B+3HCl

From the equation, it is clear that 1 mole of boron formation requires 1.5 moles of hydrogen gas.

Let's calculate the moles of boron from the given mass of boron.

No. of moles =   Mass/  Molar mass                                                                                        =  21.6g /10.8 gmol−1

= 2.00 mol
