Explanation:
As we know that density is the mass of atom divided by volume occupied by it.
Mathematically, Density = [tex]\frac{mass}{volume}[/tex]
It is given that mass is 444 grams and volume is 7 liters. Hence, calculate its density as follows.
Density = [tex]\frac{mass}{volume}[/tex]
= [tex]\frac{444 g}{7 L}[/tex]
= 63.42 g/L
Thus, we can conclude that density of the given gas is 63.42 g/L.
