# How many moles of potassium iodide, KCI, are there in 50 grams?

Apr 10, 2017

0.7 mols

#### Explanation:

To get our answer we just need to do some stoichiometry:
The molar mass of KCl is 74.55 $\frac{g}{m o l}$

50 grams KCl $\frac{1 m o l K C l}{74.55 g} = .6707 m o l s K C l$

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
