To calculate the percent composition by mass of chloroform (CHCl3), find the molar mass of each element (carbon, hydrogen, and chlorine) and the total molar mass of chloroform. Then, divide the molar mass of each element by the total molar mass and multiply by 100 to get the percentage of each element in chloroform.
