Mass % of CHCl3 = 15x10-4 %
The molar mass of chloroform (CHCl3) is 119.38 g/mol. The molar mass of chlorine in CHCl3 is 35.45 g/mol. To calculate the mass percent of chlorine, divide the molar mass of chlorine by the molar mass of chloroform and multiply by 100%. Therefore, the mass percent of chlorine in chloroform is 29.7%.
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.
The molecular formula of chloroform is CHCl3. The molar mass of chlorine is about 35.5 g/mol and the molar mass of chloroform is about 119.4 g/mol. Therefore, the percent by mass of chlorine in chloroform is (35.5 g/mol / 119.4 g/mol) x 100 = approximately 29.7%.
Each chloroform molecule (CHCl3) is composed of 25% hydrogen by mass. This is because the molecular weight of hydrogen is 1, with one hydrogen atom in each chloroform molecule, and the molecular weight of chloroform is 119.38.
To calculate the mass percent of chlorine in chloroform (CHCl3), you would first find the molar mass of the compound, which is 119.38 g/mol. Then, determine the molar mass of chlorine in the compound, which is 35.453 g/mol. Calculate the mass percent of chlorine by dividing the molar mass of chlorine by the molar mass of the compound and multiplying by 100. In this case, the mass percent of chlorine in chloroform is about 29.7%.

I think 37 percent drivers are habitual of drinking.
Each chloroform molecule (CHCl3) is composed of 12.5% carbon by mass. Carbon has a molar mass of 12.01 g/mol and accounts for one out of the four atoms in each chloroform molecule.
The reason for the water shortages is because the 70% of the earth's water is mostly salt water and contaminated water that we cannot drink.
To express 0.591 as a percent, multiply by 100: 0.591 × 100 = 59.1 %
