A60-gram sample of licl · h 2 o is heated in an open crucible until all of the water was driven off. what is the total mass of licl remaining in the crucible

42.11 g

Explanation:

Mass of the hydrated salt = 60 g

The moles of the hydrated salt is :

Amount = 60 g

Molar mass of = 60.4093 g/mol

The formula for the calculation of moles is shown below:

Thus, moles are:

After heating only LiCl remains in the crucible. So,

Moles of LiCl = 0.9932 moles

Molar mass of = 42.394 g/mol

The formula for the calculation of moles is shown below:

Also, mass is

Total mass of LiCl remaining in the crucible = 42.11 g

the dissolution of polymer can be thermodynamically described in 2 steps.
