Three students studied the following solubility curve. They were asked to determine the
amount of NHC that needs to be added to
589 MH CI to create a saturated solution at
80°C
120
Student 1 said 25 g more would need
to be added, student 2 said 22 g and
student 3 said 17g NH CI needs to be
added,
Solubility (g/100g 1,0

How many moles are in 250 grams of tungsten (w)? * 4.4x10^23 moles 4.2x10^23 moles 0.7 moles 1.4 moles

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.

Explain what happens at the saturation point when adding salt to water at room temperature.
