3 mole/ 6 kg
The molarity is 0,33.
The molarity is 0,2.
Molarity = moles of solute/Liters of solutionThat 3 kg of water would present a problem, but water = 1 gram/ml in density, so....3 kg = 3000 grams1g/ml H2O = 3000 grams H2O/X ml= 3000 ml = 3 Litersso,Molarity = 6 moles Na/3 Liters= 2 M NaOH-----------------
6 kg = 6000 grams and density of water = 1.00 grams/milliliters. 1.00 g/ml = 6000 grams/X ml = 6000 ml which = 6 liters ======================== Molarity = moles of solute/Liters of solution Molarity = 2 moles NaOH/6 Liters = 0.3 M NaOH solution -----------------------------
moles of solute over kg of solvent
4 mol over 0.800 kg

The solution is 0,25 M.
moles of solute over kg of solvent
2 mol/kg
4 mol/0.800 kg
Molality (m) is moles of solute per kg of solvent. 3 moles/6 kg = 0.5 molal.
(chemistry) the concentration of a substance in solution, expressed as the number moles of solute per kilogram of solventmolality = moles of solute / kg of solvent
1M glucose means that 1 mole of glucose is dissolved in 1kg of water. Since 1M means 1 molal. And molality is equla to no.of moles of solute per kg of water.
