As per given data, the density of the water first, the density of water first equals to 6 .2 .4 lb per feet cube.
00:18
This is feed cube.
00:19
Now the density of ethanol, density of ethanol, this is ethythaneur.
00:29
And for the first we get 49 .3 lb feet.
00:38
Now the density of ethanol 2, density of ethanol 2 equals to 6 .59 lb galon.
00:56
Unit will be changes.
00:58
Now the density of water for the second.
01:03
We just find out and in the unit lb gellon.
01:08
Now as we know that, as we know lb per gallon and the pounds per gallon are the same and pounds per gallon are same.
01:28
It means the specific gravity, specific gravity, equals to the density, density of ethanol divide by the density of water...
