Answer:

Pour 1.19 Liters of 12.6 M HCL into 3.81 Liters of water.

Explanation:

The meaning of X Molar concentration is:

The solution has X number of moles of solute per liter of liquid.

For example, the 3.00 M HCl has 3 moles of HCL per liter of liquid.

If you have 5 liters of 3 M HCl, then you have 15 moles of HCL disolved in 5 liters of water.

#(15" moles HCl")/(5" Liters") rarr 3" M HCl"#

How much 12.6 M HCL contains 15 moles of HCl?

#V = (15" moles HCl")/1(1" Liter")/(12.6" moles HCl") ~~ 1.19" Liters"#

The rest of the 5 Liters must be water.

#5" Liters" - 1.19" Liters" = 3.81" Liters"#
