swater = 1,
What good is specgrav?
- Well, u can quickly discover the mass of a substance m = sV (rearrange the formula)
- It can be used for representing density in equations where the final Pressure is not required in the question
This is good if we have the s of two liquids and their volumes, we can quickly work out the specific gravity of the mixture
100ml of water and 10ml of Hg (s = 13.6) are mixed together,
find the specific gravity of the mixture.
