A solution is made by dissolving 7.084 g of aluminum nitrate, Al(NO3)3, in 123.0 g of water. What is the mass percentage of solute in this solution?

this feels like a simple problem but i just don't know. divide the two?

mass % = [(mass solute)/mass solution)]*100 = ?
mass solute = 7.084g
mass solution = 7.084g + 123.0g = ?
