A sample of 0.72g of Al is reacted with 17mL 2.4M KOH. which one is the limiting reagent?

2Al+2KOH+6H2O------------->2KAl(OH)4+3H2

I dont know how to find limiting reagent on this case .. I think i need to know sample gram of KOH... please help me how to find out sample gram of KOH..

Thank you so much..

If you teach me how to find sample gram of KOH, then I can find limiting reagent,

3.58g/1g x 100% = 358% ??

No, the opposite. You got 1 g, that's the actual weight. Theorically, it should be 3.58 g. So, it becomes 1/3.58 x 100% = 27.9%
