What is the concentration of a solution prepared by diluting 25.0 mL of HCL 0.750 mol/L to a final volume of 500.mL?

Answer 1

mol HCl = M x L = 0.750 M x 0.025 L = ??
Then Molarity = mols/L = ??/0.500

Answer 2

0.750 M x 0.025 L = 0.01 mol

0.01 mol/0.500L = 0.02...units?

Answer 3

a 0.40 M HCl solution prepared from 25 mL of a 6.0 M HCl solution
