Calculate the concentration of each solution in mass percent.
(a) 41.2 g C12H22O11 in 498 g H2O
(b) 178 mg C6H12O6 in 4.91 g H2O
(c) 7.55 g NaCl in 155 g H2O
Answer :
(a) 41.2 g C12H22O11 in 498 g H2O
Mass %= mass of solute /mass of solution*100
=4.12/498*100
=0.82
(b) 178 mg C6H12O6 in 4.91 g H2O
Mass %= mass of solute /mass of solution*100
=178/4.91*100
=3625
(c) 7.55 g NaCl in 155 g H2O
Mass %= mass of solute /mass of solution*100
=7.55/155*100
=4.87
