what volume of a 3.95 m potassium chloride solution would be needed to make 325 ml of a 2.76 m solution by dilution?\n? ml of 3.95 m kcl
Answer
Explanation:
Step1: Use dilution formula
$M_1V_1 = M_2V_2$
Step2: Rearrange for $V_1$
$V_1=\frac{M_2V_2}{M_1}$
Step3: Substitute values
$V_1=\frac{2.76\ M\times325\ mL}{3.95\ M}$ $V_1 = 228\ mL$
Answer:
228 mL
