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_"solution" = m_"solvent" + m_"solute"#

#rarr m_"solute"=m_"solution"-m_"solvent"#

putting values in:

#m_"solute"=2000g-1500g= 500g#

Back to formula

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

#darr#

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

Hope that this helps. :)
