Recall that density is given by:
Ethyl chloride is sold as a liquid under pressure for use as a local skin anesthetic. Ethyl chloride boils at 12 °C at atmospheric pressure. When the liquid is sprayed onto the skin, it boils off, cooling and numbing the skin as it vaporizes.
Part C. The bottle shown contains 124.9 mL of ethyl chloride. The density of ethyl chloride at 25°C is 0.765 g/cm3. What is the mass of ethyl chloride in the bottle?
