Question

A solution is prepared mixing
20 glucose in 100 g of water
calculate the mass percentage
of solute
​

Answer 1

■---■---■

Mass of solute (Glucose) = 20g

Mass of solvent (Water) = 100g

We know,

Mass of solution = Mass of solute + Mass of solvent

= 20g + 100g

Mass of solution = 120g

Mass percentage of solution

$\frac{mass \: of \: solute \: }{mass \: of \: solution} \times 100$

$\frac{20}{120} \times 100$

∴ Mass percentage of solution = 16.6%
