A certain element has four stable isotopes. The first has a mass of 50.01 amu and an abundance of 8.00%. The second has a mass of 48.98 amu and an abundance of 32.6%. The third has a mass of 52.99 amu and has an abundance of 38.3%. The final has a mass of 51.98 amu and an abundance of 21.1%. Calculate the average atomic mass of the element.

C3h8o3 - glycerol major species present when dissolved in water

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.

Describe what happens to the molecules as water goes from ice to liquid to vapor. be sure to explain what happens to the temperature during the phase changes.
