Hi, in this question we have to find the density of a liquid.
00:04
Now, for number three here, this one here, mass can be calculated as, that is mass of liquid, m can be calculated as serial number 2 minus serial number 1.
00:20
So 2 minus 1 here, that is mass of cylinder plus liquid minus mass of the cylinder only.
00:27
So we get the mass of liquid.
00:29
Now, volume is given to us and density can be calculated using this formula here.
00:36
So, so for trial 1 and trial 2, number 3 can be calculated as 2 minus 1.
00:51
So it is equal to m1 mass for trial 1 is equal to 16 .95 gram minus 13 .05 gram minus 13 .05 gram so from here we get the m1 mass is equal to 3 .90 gram.
01:09
Similarly for trial 2, number 3 is equal to mass that is serial number 2 16 .90 gram minus serial number 1 that is 12 .98 gram.
01:22
So on calculating this we will get m2 mass is equal to 3 .92 gram.
01:29
That is mass of liquid for second trial...
