Here in this problem, given 18 molar h2 -so4 is diluted to get 500 milliliter of 0 .5 molar h2 -so4.
00:14
And we have to find out the volume of 18 molar h2 -s -o4, which was used for the dilution purpose.
00:23
So here we are dealing with dilution.
00:25
Let's write the formula m1 v1 is equal to m2, and v2.
00:33
V is the volume, v1 and v2, m1 is the molar concentration.
00:40
Now, the molar concentration we are starting with is 18 molar h2 -s -o -4, and its volume we have to find out, that is v1.
00:51
And after dilution, the molarity is here, 0 .5 molar.
00:57
So let's write 0 .5 molar, and the volume is 500 milliliter.
01:03
So let's write 500 milliliter...
