How to BALANCE this CHEMISTRY EQUATION?!?!?!?!

[From: ] [author: ] [Date: 11-11-29] [Hit: ]
because it balances? Can you please explain?-You balance the equation correctly. I think the book is wrong.-the book is wrong, the book I use for my students has mistakes in it.......
The equation is:
Al (s) + HNO3 (aq) --> Al(NO3)3 (aq) + H2 (g)
I got:
2Al(s) + 6HNO3 (aq) --> 2Al(NO3)3 (aq)+ 3H2 (g)

but my chemistry textbook says it's:
Al(s) + 3HNO3 (aq) --> Al(NO3)3 +H2 (g)

I don't understand how?!?!? I thought I was right, because it balances? Can you please explain?
