    1. The problem statement, all variables and given/known data
    How many grams of solid calcium hydroxide are needed to react with 14.2 mL of a 1.62 M nitric acid solution? Assume that the volume remains constant when the calcium hydroxide is added.

    Ca(OH)2 + 2 HNO3 Ca(NO3)2 + 2 H2O

    2. Relevant equations
    Molarity=moles of solute/liters of solution

    3. The attempt at a solution
    I first balanced the equation (above). I know that I will need to set up the equation above with what information I have, and that I am looking for an answer in grams. However, I really don't know how to get started. Can someone give me the general outline/procedure for what to do with a problem like this (not necessarily this problem, although it probably can be verified that it is from OWL, so, as I'm sure many of you know, I can't go in and get this same problem anyhow.

    Start calculating number of moles of nitric acid. Once you have moles it is an easy stoichiometry.
