PROBLEM 1: Physics in Substances' Quality Control. Binary solutions are mixtures of two components, such as alcohol-water solutions or sugar-water solutions. 10mL of alcohol (Alcohol = 0.789 g/mL) is mixed thoroughly with 30mL of water. a. What is the mass of the solution? (Show your complete solution) b. An important application of density measurement is quality control, not only in the soft drink or petrochemical industry, but also in the production of alcoholic beverages, cosmetics, personal care products, pharmaceuticals, and many more.
