Today i'll be going over this question.
00:03
That talks about grams of calcium and you have to convert it to grams of calcium hydroxide.
00:12
So for, in order to convert calcium to calcium hydroxide, you have to have a conversion factor.
00:23
So in each conversion factor, you have to have the, how much you are given multiplied by, a fraction and you have to make sure that the units cancel out.
00:40
So first off, you have five grams of calcium.
00:53
So the units that you would need to cancel out is grams, grams of calcium.
01:05
And the number at the bottom is going to be the molar mass of calcium.
01:09
And when you look at the periodic table, it is roughly about 40...
