We will complete the table in the picture:
2) Table sugar: also called Sucrose. It is a disaccharide
Chemical formula: C12H22O11
Molar mass: (use the periodic table) => You need to take from the periodic table the atomic masses for each element that formed the sugar table:
For C) 12.01
For H) 1.00
For O) 15.99
Then the molar mass = 12.01 x 12 (C) + 1.00 x 22 (H) + 15.99 x 11 (O) = 342.01 g/mol => the molar mass = 342.01 g/mol
Solute or solvent: Think of a cup of coffee, you need to dissolve sugar in water, therefore, it is a solute.
Ionic or covalent: Contain covalent bonds => Covalent
-----------------------------------
3) Water:
Chemical formula: H2O
Molar mass: 18 g/mol approx.
Solute or solvent: solvent (it is called universal solvent)
Ionic or covalent: covalent
