Question

This is actually for chemistry class, I need help with my worksheet in finding the number of moles with word problems. For example, the first question is: If you have 3.01x10 to the 23 molecules of AgCl, how many moles is that?

Answer 1

i got 2

Answer 2

Even though this isn't math ... you need to use Avogadro's Number, which is about 6.022 x 10^23 particles/mol

Answer 3

i'm not sure what you mean, what is that?
I don't know how to use that, i'm sorry. ^^' Could you maybe explain it to me how to use?

Answer 4

Well, we know that 1 mole of AgCl contains approximately 6.02 molecules of AgCl ( this we know by definition). If we multiply 3.01 x 10^23 molecules AgCl by (1 mol AgCl)/(6.02 x 10^23 AgCl molecules), we'll get the answer. It's just a conversion ratio.
