Explanation:
The given data is as follows.
= 211 nm, 
l = 1 cm, 7% < Transmittance < 85%
Suppose the aqueous solution follows Lambert-Beer's law. Therefore,
Absorbance = 
Hence, for 7% transmittance the value of absorbance will be as follows.
Absorbance = 
= 1.155
For 85% transmittance the value of absorbance will be as follows.
Absorbance = 
= 0.07058
According to Lambert-Beer's law.
A = 
where, A = absorbance
= molar extinction coefficient
C = concentration
Therefore, concentration for 7% absorbance is as follows.

= 
= 
= 0.187 mmol/L
Concentration for 85% absorbance is as follows.

= 
= 
= 0.01144 mmol/L
Thus, we can conclude that linear range of phenol concentration is 0.01144 mmol/L to 0.187 mmol/L.
Answer :
2 red : 2 white
Explanation:
;)long story short
hetro with hetro gives 3:1
hetro with recessive gives 1:1
Hetro :- ( Rr) one capital letter and one small
Recessive :- (rr) two small leters
