Answer:

#3.0110705 xx 10^24#

Explanation:

The number of atoms per 1 mole of any element is defined by Avogadro’s number #6.0221409 xx 10^23 mol^(-1)#

So to calculate the number of sodium atoms in 5 moles of sodium, we just multiply Avogadro’s number by 5.

#6.0221409 xx 10^23 xx 5 = 3.0110705 xx 10^24#
