Question

find w/w% of centimolar glucose solution. if density is 1.02gm/ml

Answer 1

hey .... here is ur answer .
centimolar glucose solution means 0.01M solution.
molar mass m=180g

now, molarity(M)= w/w% x d x10/m
on rearranging,
w/w% = M x m / 10 x d
. = 0.01x180 / 10x1.02
. =1.8 / 10.2
w/w% = 0.176 %
