Q
Q: If 4 moles of solute are dissolved in 2 kg of solvent, what is the molality of the solution?
Solution:
Molality (m) = moles of solute / kg of solvent = 4 moles / 2 kg = 2 m.
Steps: 6
Show Steps
Step 1: Identify the number of moles of solute. In this case, it is 4 moles.
Step 2: Identify the mass of the solvent in kilograms. Here, it is 2 kg.
Step 3: Use the formula for molality, which is molality (m) = moles of solute / kg of solvent.
Step 4: Plug in the values into the formula: m = 4 moles / 2 kg.
Step 5: Calculate the result: 4 divided by 2 equals 2.
Step 6: State the final answer: The molality of the solution is 2 m.
