of NaOH is dissolved in  of . Mole fraction of NaOH in solution and molality (in mol/kg) of the solution respectively are:

Canvas Classes · Accepted Answer

Strategy:
 Determine the moles of both Sodium Hydroxide and Water to find the mole fraction. For molality, divide the moles of  by the mass of the water (in kg).

Step 1: Calculate moles
- Moles .
- Moles .

Step 2: Calculate Mole Fraction

Step 3: Calculate Molality
