Answer:
20233.4 g
Explanation:
First, determine the moles by dividing the number of atoms by Avagadro's number.
n= (5.3 × 10^26)/(6.022 × 10^23)
n= 880.106276984
Now determine the mass by multiplying the number of moles by the molecular mass of sodium
m= n × MM
m=880.106276984 × 22.989769
m= 20233.4400033
m= 20233.4 g
