0.297 mol Br
3.37 mol Br
12.3 mol Br
1.22 × 10^47 mol Br

Answer 1

@iPwnBunnies how do you solve this given the atom

Answer 2

You use a similar conversion factor like the last one. There are 6.02 * 10^23 atoms per mole. Use the conversion factor that'll cancel out the atoms and leave you with moles.
