You have 2.72 mL of a 0.74 M solution of HCL How many moles of HC are in the solution? Now you add 4.73 ml of water, thus diluting your solution What is the new volume of your solution? What is the molarity of the new solution?

Does anyone know a lot about how to: - calculate mass of magnesium metal - calculate the actual yield of magnesium oxide - calculate the theoretical yield of mgo - calculate the percent yield of mgo - determine the percent yield of mgo - determine the average percent yield of mgo i had to do an online lab and its asking these questions but i have no idea where to start or how to be able to find these things. i can post the chart of the data from the lab or if you can tell me exactly how i can find each.
