Okay, for this problem, we are dealing with equivalence and milliequivalence per liter.
00:07
So we will first find moles per liter, and then from moles per liter, we will move on to our equivalence per liter and milliequivalence per liter.
00:18
So we need to first find our moles of calcium.
00:23
So if we have 7 .74 grams of calcium, there are 40 grams in one mole.
00:31
So 7 .74 divided by 40 is 0 .194 moles of calcium ions.
00:46
And then we take our milliliters divided by 1 ,000, and that will give us our liters, 0 .850 liters.
00:57
Okay, so then to find regular molarity, it would be moles divided by liters...
