specific gravity
 

I'm learning about specific gravity and I need a little help.

Say you have 5 bottles of sal****er solution. You know the percent of
salt each bottle contains and it's specific gravity. For example:

5% = 1.050
10% = 1.080
15% = 1.120
20% = 1.150
25% = 1.200

Now what if you had a bottle that contained an x% of salt but it's
specific gravity was 1.100. How would you calculate how much percent
of salt the bottle contains?

Anything with a substance dissolved in water, be it salt, sugar, or
whatever, that has a sg of 1.100 is always always always 10% by weight, not
volume.

The engineer in me wants to plot a graph from sample points and
then extrapolate the % for SG=1.100 from the chart. The numbers
presented here are not consistent. Are these your real readings?
If not, do you have real readings?

Looks like 12.5% to me.
