Question

glucose solution is 25% by weight of solution it's percent concentration by weight of solven is
A.20%
B.25%
C.33.3%
D.16.66%​

Answer 1

Dear Student,

◆ Answer -

(C) 33.33 %

◆ Explanation -

Consider 100 g glucose soln.

Weight of solute = 100×25/100 = 25 g

Weight of solvent = 100 - 25 = 75 g

Weight percentage of glucose w.r.t. solvent is -

% w/w = weight of solute / weight of solvent × 100

% w/w = 25/75 × 100

% w/w = 33.33 %

Therefore, concentration of glucose by weight of soln is 33.33 %.

Thanks dear...
