Answer

Explanation:

Step1: Identificar la ley de dilución

La ley de dilución es $M_1V_1 = M_2V_2$, donde $M_1$ es la concentración inicial, $V_1$ es el volumen inicial, $M_2$ es la concentración final y $V_2$ es el volumen final.

Step2: Sustituir valores dados

Tenemos $M_1 = 1.75\ M$, $V_1=84.0\ mL$ y $M_2 = 1.00\ M$. Sustituyendo en la fórmula $1.75\ M\times84.0\ mL=1.00\ M\times V_2$.

Step3: Resolver para $V_2$

$V_2=\frac{1.75\ M\times84.0\ mL}{1.00\ M}$. $V_2 = 147\ mL$.

Answer:

147
