Mole conversions

Mole conversions. QOD: Show a numerical set-up for calculating the answer to this problem. How many grams are present in 2 mol of NaNO 3 ?. Remember from yesterday…. Conversions in chemistry. Use a conversion factor that equals 1 (because we can always multiply anything that equals 1!)
