Molality is defined as moles of solute per kg of solvent. Thus, 3 moles/6 kg = 0.5 moles/kg = 0.5 m
Molality = moles solute per kg solventmoles solute = 6 moles CaCl2kg solvent = 3 kg watermolality = 6 mole/3 kg = 2 m
Morality(M)= moles of solute divided by grams of solution Molality(m)= moles of solute divided by kilograms of solvent to convert from grams to kilograms you move the decimal 3 units to the left.
10kg of water contains 10l of water. So morality is 0.2mildm-3.
2 mol/kg
Molality (m) is moles of solute per kg of solvent. 3 moles/6 kg = 0.5 molal.
This molality is 90,08 g/kg.
Molality is defined as moles of solute per kg of solvent. Thus, 3 moles/6 kg = 0.5 moles/kg = 0.5 m
3mol/6kg
3mol/6kg
Molality =moles of solute/kilograms of solvent Moles of solute =2
Molality = moles solute per kg solventmoles solute = 6 moles CaCl2kg solvent = 3 kg watermolality = 6 mole/3 kg = 2 m
Morality(M)= moles of solute divided by grams of solution Molality(m)= moles of solute divided by kilograms of solvent to convert from grams to kilograms you move the decimal 3 units to the left.
10kg of water contains 10l of water. So morality is 0.2mildm-3.
Molality(m)= moles of solute divided by kilograms(kg) of solvent you need to find the moles of NaCl by using a conversion factor 70g NaCl = 1mol divided by 58.44g NaCl =1.20mol then you need to convert 300g of water which is the solvent to kilograms by moving the decimal over 3 units to the left which makes .300 kg of solvent Molality= 1.20mol divided by .300kg Molality=4.00
2 mol/kg
convert the .2 kg of NaCl to moles of NaCl.
