If you diluted 120 mL of 1,049 M NaCl to 1,920 mL, what would
be the new concentration of NaCl? Don't put units into your
answer.
Answer:
65.56 M
Explanation:
Using the formula as follows:
C1V1 = C2V2
Where;
C1 = initial concentration (M)
C2 = final concentration (M)
V1 = initial volume (L)
V2 = final volume (L)
According to the information in this question,
C1 = 1,049 M
C2 = ?
V1 = 120 mL
V2 = 1,920 mL
Using C1V1 = C2V2
1049 × 120 = C2 × 1920
125880 = 1920C2
C2 = 125880 ÷ 1920
C2 = 65.56 M
