Answer:
9.6 mol
Explanation:
Start by writing out the balanced equation of the reaction.
2[tex]H_{2}[/tex] + [tex]O_{2}[/tex] ⇒ 2[tex]H_{2}O[/tex]
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
