00:01
So, first of all calculate the initial moles of naoh.
00:07
So, it would be equal to the molarity that is concentration which is given here in this case 0 .119 molar multiplied by the volume in liter.
00:17
So, it is volume in liter would be 0 .050 liters.
00:22
It is given that the volume here is 50 ml.
00:26
So, it would be converted to liter.
00:28
So it would be 0 .050 liters and it would be equal to 0 .00595 moles.
00:36
So this would be the initial moles of naoh.
00:40
Calculate the moles of hcl that is added to it.
00:45
So it would be equal to the molarity which is 0 .0750 molar multiplied by the volume in liters.
00:52
So it is 5 ml so it would be 0 .0050 liters...
