Question

I'm looking for the moles, using the given amount of atoms.
i was given 3.01 x 10^23 atoms of Ag
the answer I got was 18.1 x 10^23
is this correct?

Answer 1

I don't think so.
1 mol of anything contains 6.02E23 atoms; therefore, 3.01E23 is just 1/2 that so you must have 0.500 mol Ag atoms. You must have multiplied to get a number like 18 something (and if you did you left off the extra 10^23 so you didn't multiply right either).
3.01E23 atoms Ag x (1 mol/6.02E23 atoms) = ?

Answer 2

the mass in grams 6.02x10^24 atoms Bi and 1.50x10^15 atoms U

Answer 3

youre just screwed

Answer 4

6.02 x 10^24 atoms bi
