Question 2 (2.5 points)

How many grams of hydrogen are needed to react with 17.2 mol of nitrogen.
N2 + 3H2 → 2NH3
O.3g H2
06.02 x 10^23g
O 104g H2
O2.02g H2

Answer 1

`m_{H_(2)} = 51.6\,g`

Step-by-step explanation:

The mass ratio of hydrogen to nitrogen is:

`r = (6\cdot (1\,(g)/(mol) ))/(2\cdot (14\,(g)/(mol) ))`

`r = (6)/(28)`

`r = (3)/(14)`

The required mass of hydrogen is:

`m_{H_(2)} = (3)/(14)\cdot (17.2\,mol)\cdot (14\,(g)/(mol) )`

`m_{H_(2)} = 51.6\,g`
