The ultraviolet spectrum of benzonitrile shows a primary absorption band at 224 nm. If a solution of benzonitrile in water, with a concentration of 1x 10-4 molar, is examined at a wavelength of 224 nm, the absorbance is determined to be 1.30. The cell length is 1 cm. What is the molar absorptivity of this absorption band?
There are seven persons Amit, Roshan, Ravi, Priya, Amrita, Arpita and Mitul. They participated in a competition where they got different positions. Amit scored the first position while Mitul scored the last position. Priya scored fourth position from the last. Ravi scored one position higher than Priya while Amrita scored one position lower than Priya. Roshan scored higher position than five of them. Who scored the second lowest position?
There are six people Kirti, Kavita, Komal, Khushi, Koel and Kritika, who got different positions in a competition. Kavita got second position while Khushi got third position from the last. Komal’s position was immediately after Kavita and immediately before Khushi. Koel does not get either the first position or the last position. Kirti also does not get the last position. Who got the last position?
