The pH of the finsl solution is equal to <u>2.93</u>
Concentration is the abundance of a constituent divided by way of the overall volume of an aggregate. several sorts of mathematical descriptions may be outstanding: mass concentration, molar concentration, variety concentration, and extent awareness.
C₁ = 0.170 m
V₁ = 17 ml = 0.017 L
C₂ = 0.170 M
V₂ = 22 ml = 0.022 L
C₁V₁ =C₂V₂
0.170× 0.017 L = 2.89 × 10⁻³ ------------- HCl
0.170× 0.022 L = 3.74 × 10⁻³ ------------ NaOH
⇒ 3.74 × 10⁻³ - 2.89 × 10⁻³ = 0.85 × 10⁻³
⇒ 3 + log 0.85
⇒ 3 + -0.07
⇒ pH = <u>2.93</u>
The concentration of an solution is a degree of the amount of solute that has been dissolved in a given amount of solvent or solution. A focused solution is one which has a rather huge amount of dissolved solute.

Weigh them both and there you go
Answer:
The answer would be A. the number of electrons in the outermost electron shell.
Explanation:
These are called valence electrons which are transferred, shared, and rearranged by creating covalent bonds producing new substances.
Hope this helped! :)
Given that the drum is replaced each time before sampling, the selections are independent events. Then, the probability of the combined event is the product of each probability: (50/5000) * (50/5000) * (50/5000) = (1/100)^3 = 0.000001
Answer:
60 (1 hour) × 0.25 = 15 minutes
15 ÷ 16 = 0.9375 meters per minute
