This question, we're trying to find the mass or grams of hydrochloric acid available to us.
00:05
So first, let's look at the information we have about hydrochloric acid.
00:09
One, we're given the molarity.
00:12
So its molarity is one.
00:15
And then we're also told the volume, which is we have 6 .5 mils.
00:24
Now, another thing that we're going to use to help us that you can get from the periodic table is the molar mass of hydrochloric acid, which is 36 .45 grams per mole.
00:41
So we're going to use this data to find the mass.
00:47
First, remember that molarity is in units of moles per liters.
00:55
So this is like saying we have one mole of hydrochloric acid for every one liter.
01:13
So if we have one mole of hydrochloric acid for every one liter, how many moles do we have if we have 6 .5 milliliters? so we're just going to take this times 6 .5.
01:28
Before we do that, notice that this is liters, this is milliliters.
01:33
So we need to change this to milliliters by taking it times 1 ,000, right? so that's just equal to 1 ,000 milliliters...
