33.34%

#### Explanation:

To start of,

Concentration of solution by mass percent is equal to mass of solute divided by the mass of solvent multiplied by hundred

"Concentration of solution by mass %" = "mass of solute"/"mass of solvent" *100%

Mass of solvent is given: 1500 g

Mass of solution is equal to mass of solute added to mass of solvent

${m}_{\text{solution" = m_"solvent" + m_"solute}}$

$\rightarrow {m}_{\text{solute"=m_"solution"-m_"solvent}}$

putting values in:

${m}_{\text{solute}} = 2000 g - 1500 g = 500 g$

Back to formula

$\text{Concentration of solution by mass %" = "mass of solute"/"mass of solvent} \cdot 100$

$\downarrow$

"Concentration of solution by mass %" = "500g"/"1500g" *100 %= 33.34%#

Hope that this helps. :)
