Answer:

There are #1.20*10^24# atoms of sodium in #2# moles of sodium.

Explanation:

One mole of a substance is defined by Avogadro as consisting of #6.022#x#10^23# atoms. This is Avogadro's number. To calculate the number of atoms in two moles of sodium, use dimensional analysis.

#2.0# moles Na x #(6.022*10^23g)/(1mol)=1.20*10^24# atoms of Na.
