- An organic chemist measures the temperature T of a solution in a reaction flask. Here is the result. T=48.7 °C Convert T to SI units. Round your answer to 1 decimal place. OK x10arrow_forwardX 26. In the question above, two liquids react together to form solid. What term is given to this process? Precipitation Effervescence O Clumping Freezingarrow_forwardA chemistry student weighs out 72. g of an unknown solid compound X and adds it to 550. mL of distilled water at 19.° C .After 10 minutes of stirring, only some of the X has dissolved. The student drains off the solution, then washes, dries and weighs the X that did not dissolve. It weighs 64. g .arrow_forward
- A chemistry student needs 60.00 g of 2-nitroethanol for an experiment. He has available 1.2 kg of a 19.8% w/w solution of 2-nitroethanol in water. Calculate the mass of solution the student should use. Round your answer to 3 significant digits. X Sarrow_forward55. A typical rate of deposit of dust ("dustfall") from unpolluted air is 10. tons per square mile per month. What is this dustfall, expressed in mg per square meter per hour? Assume 1 ton = 2000. lbs. and 1 month = 30 days.arrow_forwardA certain liquid X has a normal boiling point of 107.80°C and a boiling point elevation constant Kb=1.02·°C·kgmol−1. A solution is prepared by dissolving some glycine (C2H5NO2) in 800.g of X. This solution boils at 109.1°C. Calculate the mass of C2H5NO2 that was dissolved. Round your answer to 2 significant digits.arrow_forward
- Chicago uses 1.2x10^9gallons of water/day. How many liters per second must be pumped from the lake every second to supply the city? (1 gal= 3.79 L)arrow_forwardSuppose that you are doing an experiment as part of your Capstone Design Project. A glass vessel originally contains 100 mL of fresh water. Then water containing 1 g/mL of NaCl is poured into the vessel at a rate of 2 mL/min, and the mixture is allowed to leave at the same rate. After 10 minutes the process is stopped, and fresh water is poured into the vessel at a rate of 2 mL/min, with the mixture again leaving at the same rate. Find the amount of NaCl in the vessel at the end of an additional 10 min.arrow_forwardA cube of sugar (p = 0.85 mg/ml) is dropped in a glass of tea at a rate of 0.02 L/sec. it take about 5 seconds for the sugar to melt completely. the weight of the sugar then equal to: 0.84 g 0.82 g 0.85 g 0.83 garrow_forward
- A certain liquid X has a normal boiling point of 146.10°C and a boiling point elevation constant =Kb1.88·°C·kgmol−1. A solution is prepared by dissolving some urea (CH4N2O) in 400.g of X. This solution boils at 149.5°C. Calculate the mass of CH4N2O that was dissolved. Round your answer to 2 significant digits. = ___garrow_forwardDennis obtained a clean, dry stoppered flask. He determined the mass of the flask and stopper to be 32.634 g.He then filled the flask with water and determined the mass of the full stoppered flask to be 59.479 g. Based on the temperature of the water, Dennis found the density of water in the Handbook of Chemistry and Physics to be 0.998730 g/mL. Calculate the volume of the flask.arrow_forwardA soda bottle is flexible enough that the volume of the bottle can change even without opening it. If you have an empty soda bottle (volume of 2.0L) at room temperature (25°C), what will the new volume be if you put it in your freezer (-4°C)?arrow_forward
