Conversion from particles to mass (g)
Ex. What is the mass of 1.27x10^22 Co atoms?
1.27x10^22 atoms x (1mol/ 6.022x10^23atoms) x (58.9g / 1 mol) = 1.24g of Co
Conversion from grams to particles
If you have 10.0g of Iron how many atoms do you have?
10.0g x (1mol/55.8g) x (6.022 x 10^23/ 1 mol) = 1.08 x 10^23
Basically just follow the steps on the mole map and make sure you cancel out the units using the fractions method depicted above.
