Alright, so here we have strontium hydroxide, neutralizing nitric acid, which makes water, and strontium nitrate.
00:27
So if you want to balance this, we'll need two nitrates on this side, which means we need two waters to balance the hydroxides and the protons.
00:38
And so this would be balanced.
00:40
So we know that we need 23 .9 milliliters of strontium hydroxide to neutralize, um, 31 .5 milliliters of the nitric acid solution.
01:06
And we want to know what is the concentration of the acid.
01:18
So what you would usually start with here, it's not given, is you would typically start with the malarity of your base.
01:27
So you have x -moles over 1 liter.
01:32
So i'm going to do this without knowing the malarity because it looks like that part was cut off here.
01:38
But if we have x -moles, um, per liter of the strontium hydroxide.
01:45
We can get rid of volume on the bottom by multiplying by how much volume we used, which is 23 .9 milliliters.
01:52
But in order to do that, we need to make sure our units cancel.
01:55
So liters, we need to turn into milliliters...
