So for this question here we need to determine quite a number of things because we are given that 0 .3 moles and 1 liter.
00:09
1 liter we can convert a liter to milliliters.
00:14
We know that formula.
00:15
So therefore the minimal of the initial solutions can be m times volume.
00:25
So this is 0 .3 multiplied by 10 to the power negative 3.
00:30
You have 300 millimole for that.
00:36
So this is acid.
00:39
Can do the same for conjugate which is 0 .3 times 10 to negative 3.
00:45
Also 300 mil for the conjugate.
00:54
Okay so if we talk about the base which is basically sodium hydroxide.
01:00
We're looking for mv also.
01:02
So this is 5 multiplied by 4 and this is 20.
01:06
A minimal of hydroxide ion from the base.
01:13
So after the reaction what we expect is that the minimal of acid that is left will be 300 minimal minus 20 minimal...
