10 g glucose is present in 100 g of son. of glucose.
Thefore,
mass of solute = 10 g
mass of solvent => 100 – 10 = 90 g
mass of soln. = 100 g
Volume of soln. = mass of soln. / density of soln. => 100/d (d being density)
Molarity of son. = moles of solute / Volume of soln. => (10/180)/(100/d) => d/1800 M
where d is the density of the soln. should be mentioned in the question.
