Expert Solution
Step 1

Given 

Mass of Sodium acetate =  12.27 gram 

Molar mass of sodium acetate =  82 gram/mole

Mass of water = 174.4 gram

                       = 0.1744 Kg                   ( 1 gram = 10-3 Kg ) 

Freezing point of water = 0 ℃ 

Molality of solution = ? 

Freezing point of solution = ?
