Answer:
The highest point on a wave is the Crest_, while the lowest point is the Trough Get a ruler and measure the wavelength and amplitude of the above wave. (a) Waves P and Q have the same frequency, but wave P has twice the What type of wave is produced when you move one end of a horizontal spring up
Explanation:
Explanation:
Using Beer-Lambert's law :
Formula used :
where,
A = absorbance of solution
c = concentration of solution
l = length of the cell
= molar absorptivity of this solution
According to question:
A = (C) : absorbance measured by the spectrometer
c = (B) : concentration, in mol/L, of the stock solution from which the sample was made
l = (A): pathlength of light through the cell
ε = (D) : molar absorptivity, a constant unique to that substance at that wavelength
Answer:
1.750 M
Explanation:
In case of titration , the following formula can be used -
M₁V₁ = M₂V₂
where ,
M₁ = concentration of acid ,
V₁ = volume of acid ,
M₂ = concentration of base,
V₂ = volume of base .
from , the question ,
M₁ = ? M
V₁ = 7.14 mL
M₂ = 0.250 M
V₂ = 50 mL
Using the above formula , the molarity of acid , can be calculated as ,
M₁V₁ = M₂V₂
M₁ * 7.14 mL = 0.250 M * 50mL
M₁ = 1.750 M
Hence, the molarity of the hydrochloric acid = 1.750 M
