So we have v1 is equals to 25 ml.
00:04
M2 equal to 0 .00383 moles.
00:11
V2 equal to 1 ,000 ml.
00:14
We know that m1 v1 equal to m2 v2.
00:19
We need to find out the value of m1.
00:22
So m1 equal to m2 v2 divided by v1.
00:28
Let us substitute the value is 0 .00383, multiplied.
00:34
With v2 ,000 ml divided by 25 ml.
00:40
M1 unsimplification gives us 0 .1532 moles.
00:48
And this is the concentration of 25 ml.
00:53
25ml concentration is 0 .1532 moles...
