Add 1.5 mL of the 1.0%(v/v) ethanol (mL) to 8.5 mL of deionized water. The ethanol standard in the test tube will have a final concentration of ____ %(v/v) ethanol?

Add 1.0 mL of wine that has been diluted by a factor of 100, to a test tube and add 20 drops of sulfuric acid to it. The concentration of the diluted wine sample was found to be 0.23%(v/v) ethanol. Using the procedure stated, what was the original concentration of ethanol in the wine? Your answer should have 2 significant figures.
