A 500 gallon tank is completely filled with water. Pure water is poured into the tank at a rate of 5 gal/min. At the same time, brine containing 2 lb of salt per gallon flows into the tank also a rate of 5 gallons per minute. The mixture flows out of the tank at a rate of 10 gal/min. What is the amount of salt in the tank after 10 minutes? O A. 32.89 lbs. O B. 45.61 lbs. O C. None of the choices O D. 22.15 lbs. O E. 90.63 lbs.
ck In the video, the water level was 15 milliliters before adding the chain, and 20 milliliters after adding the chain. When I weighed the chain, its mass was 69.1 grams. I believe the chain is solid metal (not gold plated), but is probably a blend of gold and other metals. I looked up that gold has a density of 19.3 g/ml, while the other metals like silver and copper usually blended with gold have a combined density of about 9.7 g/ml. Determine what percentage of the chain is gold, by mass, to at least 1 decimal place?
