Answer:

DIRECTIONS: Calculate for the number of moles/ grams of each of the following.

Show your complete solution and box your final answer.

1. 174 g of NaCl (Sodium Chloride)

174x (1/58.44)=2.98 moles NaCI

2. 1.60 g of KNO3 (Salitre-preservative)

160x (1/101.1)=0.0158 moles of KNO³

3. How much mass does 3.00 mol of NH3

(Ammonia) have?

3x (17.031) =51.93 g of NH³
