Here we are considering the molarities.
00:03
So, molarity, it can be written as mass divided by the molar mass.
00:17
Along with this, we can extend this line, multiplied with the volume.
00:23
And it is multiplied with the thousand if this volume, it is in ml.
00:27
So this is a formula for molarity.
00:29
Now we can find the molarity in each case.
00:33
So firstly, we see case a here.
00:38
Here, what we have? here, we have this al2 so4 has a molar mass.
00:49
Al2, so4 whole thrice will have a molar mass.
00:52
That will be equal to 342 .15 gram for one mole...
