Answer:
C₂ = 0.056 ppm
Explanation:
Given data:
Initial volume = 2.0 mL
Initial concentration = 7.0 ppm
Final volume = 250.0 mL
Final concentration = ?
Solution:
Formula:
C₁V₁ = C₂V₂
C₁ = Initial concentration
V₁ = Initial volume
C₂ = Final concentration
V₂ = Final volume
Now we will put the values in formula.
C₁V₁ = C₂V₂
7.0 ppm × 2.0 mL = C₂ × 250.0 mL
C₂ = 14.0 ppm.mL /250.0 mL
C₂ = 0.056 ppm
Gosh, I love chem!
[H2O]/t should be 0.085M/s
this is because of the coefficients in front of H2S and H2O being the same.
the significance of this answer is that the H2S disappears at the same rate H2O appears.
Answer:
NaI
Explanation:
Sodium has a charge of 1+ and iodine has a charge of 1-. They exist in a one-to-one ratio. Because they are ionic compounds, they go for the lowest ratio available.
Answer:
Explanation:
3 moles per Liter = 3 molar
Answer:
The answer to your question is: 0.25 l
Explanation:
Data
P1 = 1 atm
V1 = 0.5 l
P2 =2 atm
V2 = ?
T = constant
Formula
V1P1 = V2P2
Clear V2 from the formula
V2 = V1P1/P2
Substitution
V2 = (0.5)(1)/2 substitution
= 0.25 l result
