Answer:
44.4g
Explanation:
First we must find the moles of argon.
To do this, divide the number of atoms by Avogadro's number (6.022 ×10^23)
n= (6.7 × 10^23)/(6.022 × 10^23)
n=1.11258718034
Now to find mass, we complete the calculation
m= n × MM
where
m is mass
n is moles
MM is molecular mass
m= 1.11258718034 × 39.948
m= 44.4456326802
m= 44.4g
