Can someone . a sucrose solution is prepared to a final concentration of 0.170m . convert this value into terms of g/l, molality, and mass % (molecular weight, mwsucrose = 342.296g/mol ; density, ρsol′n = 1.02g/ml ; mass of water, mwat = 961.8g ). note that the mass of solute is included in the density of the solution,

From Molarity: we have 0.17 mole sucrose in 1 Liter solution
1) To convert it into g/L we have to multiply moles of sucrose by its molar mass:
= 0.17 mole sucrose x  = 58.2 g/L
2) Molality =  number of moles of solute / mass in kg of solvent =  = 0.177 mole / kg
3) mass % = mass of solute / mass of solution x 100 
mass of solution = 1020 g from its density
mass of solute = 1020 - 961.8 = 58.2 g solute
mass % =  x 100 = 5.7 %
