Calculate the molar mass of sulfur molecules

Reference no: EM13706435

Problem- Calculate the molar mass of sulfur molecules if 35.5 grams of sulfur are dissolved in 100.0 grams of CS2 to produce a solution that has a boiling point of 49.48 °C. Kbfor CS2 = 2.35 °C/m and its boiling point is 46.23 °C. Sulfur is a nonelectrolyte.

Please illustrate work if possible thanks
