Answer:

9.6 mol

Step-by-step explanation:

Start by writing out the balanced equation of the reaction.

2
H_(2) +
O_(2) ⇒ 2
H_(2)O

Here you will see 2 mol of hydrogen for every 1 mol of oxygen. Using this ratio, you can assume the amount of hydrogen will always be double that of oxygen. In this case, 4.8 * 2 = 9.6
