Hi there.
00:03
In this question, we are trying to prepare a molar solution, or in other words, this solution is going to have six moles of nacl in every liter of solution, because we're told that we want it to be six moles per liter.
00:20
So we have any quality there for our concentration.
00:24
We're also given the molar mass of nacl.
00:26
We are told that there are 58 .5 grams of nacl.
00:34
In every mole of nacl.
00:40
So looking at these two equalities here, we see that we can use the first one to convert from liters to moles, and then we could use the second one as a conversion factor to convert from moles to grams, which is what we're looking for is grams.
00:55
So let's go ahead and do that.
00:57
But we notice we're starting with milliliters.
01:01
We have a 250 milliliters of solutions what we're trying to make.
01:05
Well, we need that in liters so that i can use my first equality.
01:10
So we know that we can convert from milliliters to liters because there are 1 ,000 milliliters in one liter of anything.
01:18
I put milliliters in the denominator so that could be canceled...
