Web, of ethanol is 100% and the final concentration, C 2, is 70% with a final volume, V 2, of 473mL. Using the equation 1 x V 1 = 0.7 x 473mL, V 1 is calculated to be approximately 331mL, meaning the lab would mix 331mL of the 100% ethanol with 142mL of water (473-331 = 142mL) to fill the 16oz. spray bottle with 70% ethanol.
