Many common materials that we ingest, though quite safe in reasonable quantities, become toxic when taken in very large doses. A measure of toxicity is the LD 50 value (Lethal Dose, 50%). It is the quantity of material, expressed in mg of material per kg of subject-body-weight that, if administered to a population of subjects, would cause 50% of the population to die. The LD 50 value for FD&C Red Dye No. 40 is 10,000 mg/kg in rats. Assume that the LD 50 value for humans is the same as for rats. Calculate the number of number of glasses of Allura Red sports drink, each containing 8.8 mg of Allura Red, required to reach the LD 50 of 10,000 mg of Allura Red/kg body weight. Assume the person has a body weight of 165 lbs. 2.205 lbs 1 kg You may assume two significant figures but do not use sčientific notation. Do not include units with your answer.

the Daily Value for saturated fat is 20 grams (g), which equals 100% DV. If the Nutrition Facts Label says one serving of a food contains 1.5 g of saturated fat, how much % DV this meals contains from the maximum amount of fat that is recommended for you per day.
The legal limit for chromium in drinking water is 0.10 ppm. What is the maximum permissible mass of chromium (in \mu gμg) in exactly 1.0 cup (8.0 fl. oz.) of drinking water? Assume the density of drinking water is 1.00 g/mL. (1 fl. oz. = 29.57 mL)(Express your answer with two significant digits.)
O MEASUREMENT Adding or subtracting and multiplying or dividing measurements A chemistry student must write down in her lab notebook the concentration of a solution of sodium hydroxide. The concentration of a solution equals the mass of what's dissolved divided by the total volume of the solution. Here's how the student prepared the solution: • The label on the graduated cylinder says: empty weight: 1.5 g • She put some solid sodium hydroxide into the graduated cylinder and weighed it. With the sodium hydroxide added, the cylinder weighed 36.669 g. • She added water to the graduated cylinder and dissolved the sodium hydroxide completely. Then she read the total volume of the solution from the markings on the graduated cylinder. The total volume of the solution was 37.11 mL. What concentration should the student write down in her lab notebook? Be sure your answer has the correct number of significant digits. g mL Explanation -1 Check 99+ 0/5 VUDU © 2023 McGraw Hill LLC.

A geochemist measures the concentration of salt dissolved in Lake Parsons and finds a concentration of 11.10 g.L-¹. The geochemist also measures the concentration of salt in several nearby non-isolated lakes, and finds an average concentration of 4.30 g⋅L¯¹. Assuming the salt concentration in Lake Parsons before it became isolated was equal to the average salt concentration in nearby non-isolated lakes, calculate the percentage of Lake Parsons which has evaporated since it became isolated. Be sure your answer has the correct number of significant digits.
The laboratory compared the mass of the starting reactants and final products of the combustion reaction. A technician determined the mass of the firewood and oxygen reactants before burning to be 2.72 kg. After the firewood finished burning, the pile of cooled ash that remained had a mass of 0.095 kg. According to the law of conservation of mass, matter is neither created nor destroyed in a chemical reaction. Do the results of the technician’s combustion experiment contradict the law of conservation of mass?
Remdesivir is a broad-spectrum antiviral medication that is currently being used to treat Covid- 19. Remdesivir has this chemical formula: C27H35N6O3P. Since it is made up of nonmetals, Remdesivir is a molecular compound. Answer the following questions about samples of Remdesivir. 1. On the first day of treatment, a patient receives 200. mg of Remdesivir intravenously. Compute the number of molecules of Remdesivir that are delivered in this dose to the patient.
John and Eli do a reaction with the goal to prove the law os conservation of mass. In the reaction, they place 50.00 g of acetic acid (CH3COOH) in a clean, dry ziploc bag and then add 5.00 g of baking soda (NaHCO3). The products of the reaction include sodium acetate, carbon dioxide, and water. In trial 1, Eli immediately seals the bag upon addition of the baking soda and waits until the bubbling comes to a halt. John weighs the closed bag with all contents and records mass in the table. For trial 2, John and Eli repeat the procedure but forgot to seal the bag. Their results are shown in the table below. 1. Calculate the theoretical mass of the open bag. 2. Are atoms/mass conserved in each of the reactions? 3. Provide mathematical evidence to explain your reasoning that atoms/mass are/are not conserved.
