Thanks for taking the time to copy your homework to AMHD. However, the rules forbid us to give you the answer outright. Please show a little initiative and tell us what you think the answer is and why and we will be happy to help you.

We've done our homework and you can't take us with you to finals.

I'll repeat Ben's hint: How many molecules are there in a mole?
