Answer: The molar mass of the given compound is 
Explanation:
In molecular formula of
there are two chlorine atoms and one calcium atom.
The atomic mass of the calcium = 40.07 g/mol
The atomic mass of chlorine = 35.5 g/mol
Molar mass of the guven compound is :

The molar mass of the given compound is 
The volume in liters of 3245 aluminum cans is 24.8 L.
A recycling center collects 3245 aluminum cans and there are 22 aluminum cans in 1 lb. The mass of 3245 aluminum cans is:

To convert mass to volume, we need the density of aluminum (5.95 lb/L). The volume corresponding to 147.5 lb of aluminum is:

The volume in liters of 3245 aluminum cans is 24.8 L.
