Relative decreases in vapour pressure is calculated as-
equals fraction numerator in subscript NaCl over denominator straight n subscript NaCl space plus straight n subscript straight H subscript 2 straight O end subscript end fraction 0.4 equals fraction numerator straight i over denominator straight i plus 3 end fraction straight i equals 2 straight i equals 1 plus straight alpha 2 equals 1 plus straight alpha straight alpha equals 1 It space means space percent sign space ionisation equals 100 percent sign
