- 87. What volume of 0.151 N NaOH is required to neutralize 24.2 mL of 0.125 N H2SO4? What volume of 0.151 N NaOH is required to neutralize 24.2 n1L of 0.125 M H2SO4?arrow_forwardOne way to lose weight is to exercise! Walking briskly at 4.0 miles per hour for an hour consumes about 400 kcal of energy. How many hours would you have to walk at 4.0 miles per hour to lose one pound of body fat? One gram of body fat is equivalent to 7.7 kcal of energy. There are 454 g in 1 lb.arrow_forwardA martini, weighing about 5.0 oz (142 g), contains 30.0% by mass of alcohol. About 15% of the alcohol in the martini passes directly into the bloodstream (7.0 L for an adult). Estimate the concentration of alcohol in the blood (g/cm3) of a person who drinks two martinis before dinner. (A concentration of 0.00080 g/cm3 or more is frequently considered indicative of intoxication in a normal adult.)arrow_forward
- "Vinyl chloride [monomer (VCM, C₂H3CI)] is one of the most widely-used industrial chemicals (about 3 x 1010 kg produced each year for making PVC plastic)" and is in the news lately due to the train derailment in East Palestine, OH. "It is also one of the most toxic chemicals and a known carinogen. The maximum concentration of vinyl chloride allowed in drinking water in the United States is 0.002 mg/L."arrow_forwardAn injectable preparation comes packaged as a 4 g vial and states that you should add 35 mL to achieve a final concentration of 200 mg/2 mL. How much diluent should you add to achieve a final concentration of 125 mg/2 mL? O a. 52 mL O b.59 mL O c. 55 mL O d. 48 mLarrow_forwardWhich of these will NOT dissolve in water? a.table salt b.sugar c.vinegar d.bacon fatarrow_forward
- An action will elevate the concentrations of three chemicals in the drinking water supply: 1,1,1- trichloroethane to 2 mg/L, tetrachloroethylene to 0.04 mg/L and 1,1-dichloroethylene to 0.1 mg/L. Determine the lifetime risk of developing an undesirable health effect due to this exposure for a 50 kg adult who drinks 1 L/day of water containing these elevated pollution levels. Is there cause for concern? Why?arrow_forward1. You have a concentrated stock solution of bacterial LPS in water that has a concentration of 1 mg/ml. What is the concentration of a diluted solution with a dilution factor of 1:2? 2. Your stock solution is 1 mg/ml and your final solution is 1ug/ml. What is your dilution factor? 3. A 1 ug/ml solution is diluted so it is half as concentrated as the stock. What is the concentration of the new solution in ng/ml?arrow_forward4. Calcium Hydroxide Solution (Lime Water) and olive oil are used because an emulsifying agent is formed in situ when these 2 solutions are agitated together. What is the emulsifying agent that is formed? a. calcium succinate b. calcium oleate c. succinic hydroxide d. palmitic hydroxidearrow_forward
- A tank initially contains 200 liters of fresh water. Brine containing 2.5 N/liter of dissolved salt runs into the tank at the rate of 8 liters/min and the mixture kept uniform by stirring runs out at the same rate. After 15 minutes, what is the concentrations of the salt in the mixture? 1.1 N/L 1.8 N/L 2.1 N/L 0.82 N/Larrow_forward1 What mass of solid radium sulfate (the most insoluble compound known) will remain when 10 L of a saturated solution is transferred to a new container and the water evaporated to complete dryness? Ksp for RaSO4 = 4.30 x 10–11. a. 0.0021 g b. 0.021 g c. 0.071 g d. 0.710 g e. 0.0070 garrow_forward1. 0.5 liters of saltwater having a chloride concentration of 27,500 mg/L is added to 10 liters of NYC tap water having a chloride concentration of 10.0 mg/L. a. Draw a diagram and write the appropriate mass balance equation. b. Calculate the concentration of chloride in the mixture. c. Would the chloride concentration in the mixture meet the NYS Department of Health Maximum Contaminant Level (MCL) of 250 mg/L?arrow_forward
