NEED HELP FAST!! How many g NiCl2 are present in 0.200L of a 1.20M NiCl2 solution?

Calculate the molarity of 2.70L of a solution that contains 145.50g HClO3.

What volume of a 0.20M RbF2 solution contains 25.00g RbF2?

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.
