A)0.012 M
B)0.12 M
C)1.2 M
D)12 M
E)120 M

The concentration after dilution can be calculated using the formula $C_1V_1 = C_2V_2$, where $C_1$ and $C_2$ are the initial and final concentrations, and $V_1$ and $V_2$ are the initial and final volumes. Substituting the given values: $3.0\,M \times 100\,mL = C_2 \times 250\,mL$. Solving for $C_2$ gives $C_2 = 1.2\,M$.
