Respuesta :

To solve this question, we need to use the following formula:

Percent by mass = (Mass of solute/mass of solute + mass of solvent) x 100%

mass of solution = mass of solvent + mass of solute

mass of solute = 98 g

mass of solution = 534 g

Percent by mass = (98/534) x 100%

Percent by mass = 18.4%

Answer: Percent by mass = 18.4%
