Here, if we see we are having a picnometer and it is given that weight of the picnometer, it is 25 gram.
00:08
And when it is filled with water, then picnometer weight with the motor, it is approximately given as, it will be given as 65 grams.
00:23
And along with this, when this picnometer, it is filled with unknown liquid, the weight it is 52 gram.
00:31
So here we have to find the specific gravity for the unknown liquid.
00:38
So specific gravity in this particular case can be calculated as firstly we should know this mark of picnometer.
00:49
Mass of the picnometer with the liquid, it is 52 gram.
00:54
And from this we have to subtract the mass of the empathy picnometer, which is 25 here in this case.
01:02
So it will become let us say, this.
01:04
Mass it is m2, it is here m1 and here it is m3.
01:13
So here this is the thing here now it will become m3 minus m1 divided by the mass of the pichnometer filled with this thing we can say mass of peknometer with this liquid m3 and along with this we should subtract m1 which is empty pichnometer.
01:36
Similarly, mass of the picnometer with this, we can write this mass of picnometer plus liquid plus water...
