What is the molality of a solution made by dissolving 2 moles of NaOH in 6 kg of water?
O A. 0.33 mol/kg
B. 12 mol/kg
O C. 2 mol/kg
O D. 3 mol/kg

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be

fe 55.85 g/mol and h2o 18.02 g/mol.

the answer is d. 74.02
