Here it is asked that what volume of k -o -h solution is needed where the concentration of k -h solution is given as 0 .2450 molar.
00:13
To neutralize the solution of s3po4 having the volume 55 .25 milliter and the concentration is 0 .544 -0 molar.
00:27
And there are five options are given.
00:31
First one is 165 .8mm, 368 .0 milliliter or 30 .066mm or 90 .17 milliliter or 22 .0 milliliter.
00:47
First we need to find out number of moles of h3po4.
00:53
So let's find out.
01:03
So we will put the formula as.
01:05
Number of moles will be volume multiplied by molarity.
01:16
As we already know that, molarity is number of moles per volume.
01:22
So, so here we'll put the values and let's calculate the number of moles.
01:30
Volume is given as 55 .25 and the molarity as 0 .5 -440...
