(a) 0.2% w/v normal saline solution(conc<0.9% w/v(b)3% w/v dextrose solution(c)1% w/v boric acid solution

(1)2.0% w/v normal saline sol(conc.>0.9% w/v(2)10% w/v dextrose solution (3) 3%w/v boric acid solution

(a)0.9% w/v normal saline(b)5.0% w/v dextrose solution(c) 2.0% w/v boric acid solution

1.8% UREA SOLUTION HAS SAME OSMOTIC PRESSURE AS THAT OF 0.9% NaCl
