Calculate the number of moles of h2o removed and the moles of anhydrous cucl2 remaining in the crucible?

6.The moles of water can be gotten by dividing the mass of water in step 5 by the molecular mass of water(18.01528 g/mol).

7 The moles of the dried copper salt can be calculated  by dividing he mass of dried salt in step 4 by the molecular mass of CuCl2 (134.4620 g/mol).

Look below for further explanation

Explanation:

Assumption:The  lab experiment involved heating copper (II) chloride dihydrate in a crucible to remove the water.(hydrate)  

1. weigh and record the mass of  an empty crucible (tare wt).  

2.Add the copper hydrate salt, and reweigh (total  wt). The mass of the added hydrate salt can be derived by subtracting the tare wt from the total weight wt (= net wt of the hydrate).  

3.The next is to heat the crucible at some temperature above 100 C until the mass of the crucible plus dried salt is known to be constant (cool the crucible in a dessicator).  

4.The mass of the dried salt is obtained by subtracting the tare wt from the mass of the crucible plus dried salt. (mass of dried salt)

5.The mass of water is calculated by subtracting the mass of the dried salt from the mass of the hydrate salt.(in step 2)  

6.The moles of water can be gotten by dividing the mass of water in step 5 by the molecular mass of water(18.01528 g/mol).

7 The moles of the dried copper salt can be calculated  by dividing he mass of dried salt in step 4 by the molecular mass of CuCl2 (134.4620 g/mol).

when—without warning—something provokes your anger, you may struggle not to succumb to it. since what typically makes you mad is feeling powerless in the face of what seems unfair, your anger is mostly an attempt at a “quick fix” to right the balance. it’s as though you’re raising a fist in protest, proclaiming that you’re not going to capitulate to such injustice.

there are, however, a multitude of problems related to this immediate, push-back reaction of anger. and probably the key one is that almost never does it resolve the issue that gave rise to it. such reactive anger is probably best understood as self-defeating. as david burns, the author of the seminal self- book feeling good, observes: if realistically, acting on your anger is to make any sense, it needs to meet two criteria—which, in almost every case, is frankly impossible. that is, your anger must:

be directed toward a person who has intentionally (and needlessly) behaved in a hurtful way toward you; and

be beneficial or advantageous to you (i.e., assist you in achieving a desired goal).

i think you’ll agree that only rarely can you claim that your anger is both warranted and , whether to yourself or the relationship.

so let me offer you a two-step alternative to abandoning your better judgment and giving in to the temptation of anger—one that should neutralize your anger in seconds. or, when you’re really angry, in minutes.

but keep in mind that you must really want to execute these steps, be sufficiently motivated to perform them. which means overcoming more unconscious resistance than you might ever have imagined. because there are many immediate “advantages” of anger that can interfere with your resolve, i’ll suggest a few of them that might interfere with your employing this powerful method to rid yourself of counter-productive anger.
