STOICHIOMETRY: QUANTITATIVE INFORMATION ABOUT CHEMICAL REACTIONS

Question

If you dilute 35.0 mL of 1.75 M hydrochloric acid to 600. mL, what is the molar concentration of the dilute acid?

Molar concentration=____M

Answer 1

For this, you can use V1M1 = V2M2

(35.0 ml)(1.75 M) = (500 ml)(x M)

x = 0.1225 M = 0.123 M (3 significant figures)
