An aqueous solution containing 3.42 grams per woo grams of water had a freezing point depression of 0.186°c.calculate mass of solute
Expert's answer
"\\Delta T=KC_m=K\u00b7\\frac{m_{salt}}{M_{salt}\u00b7m_{H_2O(kg)}}"
"M_{salt}=\\frac{K\u00b7m_{salt}}{\\Delta T\u00b7m_{H_2O(kg)}}=\\frac{1.86\u00b73.42}{0.186\u00b70.001}=34200g\/mol"
