How many moles are in 29.6 g sodium chloride

The answer is 0, 506 mol

Explanation:

We calculate the weight of 1 mol of NaCl:

Weight 1 mol NaCl = Weight Na + Weight Cl= 23 g + 35, 5 g = 58, 5 g

58, 5 g1 mol NaCl

29, 6 gx= (29,6g x 1 mol NaCl)/ 58,5 g = 0,505982906 mol NaCl

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).

i think its 100.

hope this !
