"The coronavirus disease (COVID-19) is an infectious disease caused by a new strain of coronavirus. This new virus and disease were unknown before the outbreak began in Wuhan, China, in December 2019. On 30 January 2020, the Philippine Department of Health reported the first case of COVID-19 in the country with a 38-year-old female Chinese national. On 7 March, the first local transmission of COVID-19 was confirmed. WHO is working closely with the Department of Health in responding to the COVID-19 outbreak." Aki and her family were alarmed with fhe news they watched and so first thing in the morning they rush to the nearest convenient store to secure disinfectant and sanitizers but unfortunately the store aiready had empty shelves of the essentials they needed. They went to other stores searching and to their dismay they acquired nothing. They were on their way home when she suddenly remembered her past lesson on "solutions", and so she immediately ran back to the store and purchase the things she needed for her simple experiment. She bought a bleach (Zonrox), gloves and measuring spoon and cups. Arriving at home she then put her gloves on and prepared the things she needed such as; 5tbsp bleach (0.0739L), 1 gallon of water (3.8L), pail and stirring rods. Using the pail with 3.8L of water, she carefully poured the 5tbsp bleach solution and then mixed it with the stirring rod. And they now have a disinfectant. In connection to her home made disinfectant and with our lesson, we will express her solutions' concentration into, different units; Molarity, Molality, Percent by mass, Percent by volume, mole fraction and ppm. Questions: 1. What is the molar concentration of Aki's disinfectant if she dissolved 5Tbsp. of NaCIO (sodium hypochlorite) in 3.8 liters of H2O (water)? 2. Compute for the molality of her disinfectant if she dissolved 5Tbsp. of NaCIO (sodium hypochlorite) in 3.8 liters of H20 (water). 3. Calculate the percent by mass of sodium hypochorite in her disinfectant solution. ( 5Tbsp. of NaCIO (sodium hypochlorite) and 3.8 liters of H2O (water). In units of grams for both of the solute and solvent. 4. Calculate the mole fraction of sodium hypochorite and water in Aki's solution. ( 5Tbsp. of NaCIO (sodium hypochlorite) and 3.8 liters of H20 (water). 5. Calculate the percent by volume of the disinfectant Aki made. Units in mL. 6. What is the concentration of her solution in parts per million? ( 5Tbsp. of NaCIO (sodium hypochlorite) and 3.8 liters of H2O (water).
