Answer 1

25 ml of 0.10 M R enantiomis = 25,x0.CM) Renante'omen = (25x0.4) mmol R enanteomen 25 mmol R enantiomer 45 x - 0.4 (4) 3 * (75x0.4 mmol S it.5 mmol som total solution -is 100 ml 01] (042 = 10.0 mmal gay specefie notation of R enanti'omui -is se? as we know specific rotation of 's' and 'r enantiomer is same in value but opposite in sign. 2.5 mmol of a specific notation 7.5 mmol of x and resultant is 10.0 monol of +2.6 specific retention 205x3 + 1.5*(-2): 10.0X416 64.5+ 2.54% = 10.024.6 - 5.0xx 10.0 X416 2 2 = - 100x4.6 -2x4.6 =(-9:2)
