Answer:
8.90 M
Explanation:
Step 1: Given data
-
Initial concentration (C₁): ?
- Initial volume (V₁): 635 mL = 0.635 L
- Final concentration (C₂): 5.00 M
- Final volume (V₂): 1.13 L
Step 2: Calculate the initial concentration
We have a concentrated NaCl solution and we want to prepare a diluted one. We will use the dilution rule.
<em>
C₁ × V₁ = C₂ × V₂
</em>
C₁ = C₂ × V₂ / V₁
C₁ = 5.00 M × 1.13 L / 0.635 L
C₁ = 8.90 M

Answer: C the study of living things
Explanation:
To convert milliliters to liters, you should divide the milliliters by 1000. When we do that here, we will see that there are 0.0456 liters in 45.6 milliliters.
