1. 0.54 g of ammonium chloride is dissolved in 250 mL of solution. Calculate the molarity.
Solution: Molecular weight of Ammonium Chloride = 14+4+35.5 = 53.5 grams/mole
Number of moles of NH4Cl = 0.54/53.4 = 0.01011
Therefore Molarity = 0.01011/0.25 = 0.04M
2. What volume of solution would be required to deliver 6.84 g of 0.200 M aluminum sulfate solution?
Molarity = (Mass of ...
