Answer:
He needs to add 4 mL of the 0.5 M solution to 6 mL of water.
Because it represents 2 atoms of carbon not 2 molecules of carbon
The amount of the solute is constant during dilution. So the mole number of HCl is 2*1.5=3 mole. The volume of HCl stock is 3/12=0.25 L. So using 0.25 L stock solution and dilute to 2.0 L.
.5 mols
Assuming that your 2.0 m is an M for molarity
I used the formula M=number of mold/L
Converted 250mL to .250L by dividing by 1000
