What volume of 1.0 M #CuSO_4# would you need to make .750 L of a .20 M solution?

Answer 1

Peyton Adams

#0.150*L# are required.

#"Concentration"# #=# #"Moles of solute"/"Volume of solution"#.

And thus #"Moles of solute "(n)# #=# #"Concentration "(mol*L^-1)xx"volume "(L)#

In the required volume there are #0.750*Lxx0.20*mol*L^-1# #=# #0.150*mol#.

Thus, in the starting volume, we need #0.150*L#, which contains #0.150*mol#. This volume is then diluted to #0.750*L#.

To make a 0.20 M solution of CuSO4 with a final volume of 0.750 L, you would need to dilute 0.375 L of a 1.0 M CuSO4 solution with 0.375 L of water.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
