If 25.00 mL of 6.00 M HCl is transferred by pipet into a volumetric flask and diluted to 5.00 L, what is the molarity of the diluted HCl?

a) 0.75 M
b) 0.055 M
c) 1.20 x 103 M
d) 48.0 M
e) 0.0300 M

grams of solute/molar mass of solute/liters of solution?

1 answer

the volume has increased by a factor of 200, so the molarity has decreased by the same amount.

6.00/200 = 0.03
