A solution of sodium chloride (NaCl) has a concentration of 0.1 M. If 10 mL of this solution is diluted to a total volume of 50 mL, what is the new concentration of the solution?
Answer Options
Correct Answer
A.
\text{New concentration} = \frac{0.1 \text{ M} \times 10 \text{ mL}}{50 \text{ mL}} \times \frac{1 \text{ M}}{1 \text{ M}}
B.
\text{New concentration} = \frac{0.1 \text{ M} \times 10 \text{ mL}}{50 \text{ mL}} \times \frac{1 \text{ M}}{1 \text{ M}} \times \frac{1 \text{ M}}{1 \text{ M}}
C.
\text{New concentration} = \frac{0.1 \text{ M} \times 10 \text{ mL}}{50 \text{ mL}} \times \frac{1 \text{ M}}{1 \text{ M}} \times \frac{1 \text{ M}}{1 \text{ M}} \times \frac{1 \text{ M}}{1 \text{ M}}
D.
\text{New concentration} = \frac{0.1 \text{ M} \times 10 \text{ mL}}{50 \text{ mL}} \times \frac{1 \text{ M}}{1 \text{ M}} \times \frac{1 \text{ M}}{1 \text{ M}} \times \frac{1 \text{ M}}{1 \text{ M}} \times \frac{1 \text{ M}}{1 \text{ M}}
Correct Answer
A
Correct Option:
\text{New concentration} = \frac{0.1 \text{ M} \times 10 \text{ mL}}{50 \text{ mL}} \times \frac{1 \text{ M}}{1 \text{ M}}
