Hello there!
<span> Use Avogadro's number, 1 mol = 6.02 x 10^23 atoms.
</span>Convert atoms to moles and you get:
<span>9.97x10^(-15) moles Co
</span>
Hope This Helps You!
Good Luck :)
The mass of cobalt (III) needed is
m = 5.2 L (0.42 mol/L) ( 93 g/mol)
m = 97.65 g
The volume of nitric acid needed is
V = 5.2 L (0.42 mol/L) (3 mol / 1 mol) (1000 mL/1.6 mol)
V = 1968.75 mL
The moles of water produced is
n = 5.2 L (0.42 mol/L) (3 mol / 1 mol)
n = 3.15 moles
