You have 2 moles of NaOH how many molecules of NaOH?
kaheart [24]

Answer:

12.044 X 10^23 molecules of NaOH

Explanation:

because NaOH is an ionic bond, we should be asking how many <em>formula units </em> are in 2 moles of NaOH, there are 0 molecules since NaOH is measured in formula units.

but for the sake of the problem I'll assume NaOH is measured in molecules

for every mol of something there are 6.022 X 10^23 of something of that something.

so there are 6.022 X 10^23 molecules for every mol of NaOH

that means we have 2 X 6.022 X 10^23 molecules in 2 moles of NaOH = 12.044 X 10^23 molecules of NaOH
