Answer:
0.67mol/Kg
Explanation:
The following were obtained from the question:
Mole of solute = 0.50mol
Mass of solvent = 750g = 750/1000 = 0.75Kg
Molality =?
Molality = mole of solute /mass of solvent
Molality = 0.5/0.75
Molality = 0.67mol/Kg
Larynx connects the pharynx to the trachea and is also part of the respiratory system
The first one will be 2 1 -> 2 1
Second is 2 3 -> 6 1
