Astudent measures the mass of a metal bar as 57.21 g. the student fills a graduated cylinder with water and determines the volume of water to be 53.70 ml. the student places the metal bar into the graduated cylinder and records the new volume as 58.80 ml. calculate the density of the metal bar and identify it from the choices that appear in table 1.1.

150.0 grams of asf3 were reacted with 180.0 g of ccl4 to produce ascl3 and ccl2f2. if the actual yield of ccl2f2 was 127 g, what is the percent yield?

The diagram below shows a cell placed in a solution.a cell is shown placed inside a beaker. it is labeled cell. the solution inside the beaker is labeled 40% salt solution and the solution inside the cell is labeled 20% salt solution.only water is allowed to move in and out of the cell. what will most likely happen to the cell? it will expand as water moves out of it. it will shrink as water moves out of it.it will expand as water moves into it. it will shrink as water moves into it.
