0.7 mols

Explanation:

To get our answer we just need to do some stoichiometry:
The molar mass of KCl is 74.55 #g/(mol)#

50 grams KCl #(1 mol KCl) /(74.55 g)= .6707 mols KCl#

As presented this problem is rounded to 1 sig fig since 50 grams is 1 sig fig.

Thus the rounded answer would be 0.7 mols
