Question:
If {eq}55 \ mL {/eq} of {eq}3.2 \ M \ HCl {/eq} is used to make a {eq}350 \ mL {/eq} aqueous solution, what is the {eq}molarity {/eq} of the dilute solution?
Dilution Formula: Fundamental Concepts
Consider a particular solution with an initial molarity {eq}c_1 {/eq} and volume of the stock solution {eq}V_1 {/eq}. If the original solution is diluted to a final volume {eq}V_2 {/eq}, its molarity can be found from the relationship {eq}c_1V_1 = c_2V_2 {/eq}. This formula is valid, since:
- Dilution only adds water to the solution
- The mass of the solute remains unchanged
- {eq}c_1V_1 = c_2V_2 {/eq} represents the fact that the moles of the solute initially and finally is exactly same

View this answerGiven the initial solution with:
{eq}c_1 = 3.2~M\\ V_1 = 55~mL {/eq}
And the volume of the final solution:
{eq}V_2 = 350~mL {/eq}
According to...
