Question

1. (\frac{5}{5}+\frac{2}{2}) 10. dilution ((c_1v_1 = c_2v_2)): ((0.50m)(x ml)=(0.10m)(250 ml))

Explanation:

Step1: Write the dilution formula

$C_1V_1 = C_2V_2$

Step2: Substitute given values

$(0.50\ M)x=(0.10\ M)(250\ mL)$

Step3: Solve for $x$

$x=\frac{(0.10\ M)(250\ mL)}{0.50\ M}$
$x = 50\ mL$

Answer:

$50\ mL$
