In this video, we are going to use dimensional analysis to solve a problem pertaining to the administration of certain saline solution.
00:10
And we have the molarity given.
00:14
And we want to administer a certain amount of grams.
00:18
So it's just a conversion of basically mulstagrams.
00:21
All right.
00:22
So we're told that the patient in question weighs 60 kilograms and wants two milligrams of an item.
00:30
Nicl per kilogram of body weight.
00:32
So two milligrams of nicl for every one kilogram.
00:37
And we're also given that we have 0 .154 molar nacl.
00:44
So this is equal to 0 .154 moles in every one liter of solution.
00:51
So if we have milligrams, we need to go to grams and then to moles.
00:54
All right.
00:55
So one gram is equal to 1 ,000 milligrams.
01:00
And then from the molar mass, if you add up the masses of an acl, the periodic table, you get that one mole is equal to 58 .45 grams...
