what is the percent by weight (w/w%) of sugar in soda? assume the average mass of sugar in soda is 35.0 g and the total mass is 370.0 g.

Respuesta :

The percent by weight (w/w%) of sugar in soda : 9.459 %

To find the percentage the given data's are:

mass of sugar = 35 g

total mass = 370 g

What is the percent weight?

  • Percent by weight is also known as Mass percent composition.
  • It is abbreviated as w/w%.
  • For a solution, mass percent equals the mass of an element in one mole of the compound divided by the molar mass of the compound, multiplied by 100%.

Solution for the given values are,

%weight = (mass of solute : mass of solution) x 100%

Mass of solute = Mass of sugar = 35 grams

Mass of solution = Mass of ( solvent + solute) = water + sugar = 370 grams

The percent weight of sugar in soda :

= (35 : 370) x 100%

= 0.0945945

= 9.459 %
