If 2.4 g of calcium hydroxide reacted with nitric acid, calculate the number of moles of calcium hydroxide used.  

You can still receive full marks for this question if you did not get the previous question correct, but you MUST show all work starting with the formula (and rearrangement if needed) to determine moles, then the substitution of values into the formula, then the calculated answer.  You then need to remember to include units and use correct significant digits in your final answer.  Responses only showing the final answer will receive a zero grade.

Note, to show division please use the "slash" symbol on your keyboard under the question mark.  

For example, 4/8 = 0.5
