Answer

Answer:

B. 0.665 mol/L

Explanation:

Step1: Convert initial volume to L

$V_1 = 37\ mL=37\times10^{- 3}\ L = 0.037\ L$

Step2: Use dilution formula $C_1V_1 = C_2V_2$

$C_1 = 10.25\ mol/L$, $V_1=0.037\ L$, $V_2 = 2.40\ L$. We need to find $C_2$. $C_2=\frac{C_1V_1}{V_2}$

Step3: Substitute values and calculate

$C_2=\frac{10.25\ mol/L\times0.037\ L}{2.40\ L}=\frac{0.37925\ mol}{2.40\ L}\approx0.665\ mol/L$
