What is the molarity of the resulting solution when 300.mL of a 0.400 M solution is diluted to 800.mL?
A)0.109 M
B)0.150 M
C)1.07 M
D)1.47 M

Quizplus · Accepted Answer

The molarity after dilution can be calculated using the formula $M_1V_1 = M_2V_2$, where $M_1$ and $V_1$ are the initial molarity and volume, and $M_2$ and $V_2$ are the final molarity and volume, respectively. Substituting the given values, $0.400 \, \text{M} \times 300 \, \text{mL} = M_2 \times 800 \, \text{mL}$. Solving for $M_2$ gives $M_2 = 0.150 \, \text{M}$.
