3.6 grams of boron react with 1.0 grams of hydrogen to give 4.6 grams of BH3.
How many grams of boron would react with 3.3 grams of hydrogen???

Respuesta :

znk

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
