The density of water at 30.0 °C is 0.9956 g/mL. If the specific gravity of acetic acid is 0.1040 at 30.0 °C, what is the density of acetic acid at 30.0 °C?

• chemistry -

Specific gravity (S.G.)=Density of acetic acid/density of H2O

Solve for density of acetic acid.

S.G.* density of H2O=density of acetic acid

(0.1040*(0.9956 g/mL)=S.G.

what is osmosis

• chemistry -

The tendency of water/solvent to flow from concentrations where solute concentrations are high across a membrane to concentrations where solute concentrations are low to give an equal water/solvent to solute ratio on both sides of the membrane.

• chemistry -

This looks reversed to me.
http://en.wikipedia.org/wiki/Osmosis

Water flows from low solute concns to high solute concns; it's making the higher concns more dilute in order to equalize the concns on both sides of the membrane.

He's right it's from low solute to high. It was late and I was tired.
