Thanks for helping. I get it now. ^____^

Determine the number of atoms in 2.25 moles of nitrogen gas. I'm confused >.< Do I: 1) multiply 2.25 mol by 6.02 x 10^23 atoms or or 2) multiply 2.25 mol x 6.02 x 10^23 molcules x 2 atoms. or is it something else? Also, how do I do this problem? Calculate the mass of 3.01 x 10^23 formula units (ions) of Strontium hydroxide. Please help if you can. ~____~

I'm doing a science fair project and need help on finding a plant (the seeds) that grows real fast (like lima beans) and can be grown in a cold/winter climate. I would buy lima beans, but it's very hard to find a place where it's available. :'(((( [i hope I posted this in the right section, if not please move it. ^__^]

Hay everone! This seems like a pretty decent forum. I don't like science, but chemistry really interests me.
