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.

Answer:
Mechanical energy is basically the energy of movement
For example, if I am running, im using Mechanical energy
Acceleration is defined as velocity per unit time.


Here, a=acceleartion,
v=velocity=36 m/s
t=time=12 s



A car at rest ends accelerates for 12 seconds. After this time the car is going 36 m/s. So acceleration that is a=3 ms⁻².
