The molecular weight of table salt, NaCl, is 58.5 g/mol. A tablespoon of salt weighs 6.37 grams. Calculate the number of moles of salt in one tablespoon.
First, complete the unit conversion using dimensional analysis:
А х
B
С
? mol Naci

.109 moles

A = 6.37

B = 1

C = 58.5

Explanation:

Given : molecular weight of NaCl : 58.5g / mol

We want to calculate the number of moles in a tablespoon of NaCl which weighs 6.37 grams.

To do so we can use dimensional analysis.

the units cancel out and we have to divide 6.37 by 58.5 to get .109 ( rounded to 3 sig figs )

So there are .109 moles in a tablespoon of salt

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
