Question 3- Pharmaceutical Calculations. A. If you know that sodium bicarbonate has a solubility of 8.4 g in 100g at 18 °C I. Calculate (a) the molarity and (b) the molality of 8.4 g of Sodium bicarbonate in water. Molarity= moles in 1 Litre. Questions asking how many moles os sodium bicarbonate in 1 L solution (I think you need the molecular weight to calculate part A, not sure if it provided above cannot see it,but dont quote me) II. if you had 200 mls of water, what is the minimum amount of Sodium bicarbonate that you will require to achieve supersaturation?
