Question

How many atoms of Na are in 1.89 mol of Na?

Answer 1

1.138158E24 atoms or 1.14 x 10^24 atoms

Step-by-step explanation:

To find atoms/particles from moles you just want to convert using avogadro's number which is 6.022 x 10^23

1.89 mol x 6.022 • 10^23

———— = 1.138158E24 atoms

1 mol

so 1.138158E24 atoms or 1.14 x 10^24 for scientific notation

hope this helps :)
