Question

]If a sample of pure iodine contains 4.69 x 1022 atoms of iodine, how many moles of iodine are in the sample?
0.08 mol

0.13 mol

7.78 mol

12.84 mol

Answer 1

thank you :)

Answer 2

Use avogadro's number to convert. Avogadro's number is: \(6.022 \times 10^{23}\frac{ mol }{ atom }\)

Answer 3

answer please

Answer 4

????????

Answer 5

You have to try figuring it out yourself first. I gave you the units.
What you're doing is just like algebra, cancelling out units
HINT: divide

Answer 6

\(4.69 \times 10^{22} \frac{ \cancel{atoms} }{ 1 } \times \frac{ mol }{ 6.022 \times 10^{23}\cancel{atoms} }=\) ??
