A stock solution is made by dissolving 66. 05 g of (nh4)2so4 in enough water to make 250 ml of solution. A 10. 0 ml sample of this solution is then diluted to 50. 0 ml. Given that the molar mass of (nh4)2so4 is 132. 1 g/mol, what is the concentration of the new solution? use m subscript i v subscript i equals m subscript f v subscript f. And molarity equals startfraction moles of solute over liters of solution endfraction. 0. 400 m 1. 60 m 5. 00 m 10. 0 m.

Analyze the analogy and read the information below it. fish : fin : : bird : wing if you were reading this aloud, you would say, "fish is to fin as bird is to wing." this analogy uses parts of an animal to relate to the whole animal. much like how a fin a fish move, so does a wing a bird move. which analogy also uses parts to relate to the whole? sky : blue : : dirt : brown flower : petal : : tree : leaf car : road : : boat : water food : sandwich : : sport : softball
