Respuesta :
The hydrogen will react with 12 g B
Mass of B = 3.3 g H_2 × (3.6 g B/1.0 g H_2) = 12 g B
The mass of boron that will react with 3.3 g of Hydrogen is 11.88 g
From the question given above, we were told that 3.6 g of boron react with 1.0 g of hydrogen to give 4.6 grams of BH3.
With the above information in mind, we can obtain the mass of boron needed to react with 3.3 g of hydrogen. This can be obtained as follow:
From the question given above,
3.6 g of boron react with 1.0 g of hydrogen
Therefore, Xg of boron will react with 3.3 g of Hydrogen i.e
Xg of boron = 3.6 × 3.3
Xg of boron = 11.88 g
Thus, we can conclude that 11.88 g of boron will react with 3.3 g of Hydrogen
