Calculation of Chlorine Mass for Chloroform Production

To determine the mass of chlorine needed to produce 243 kg of chloroform from dichloromethane, we need to consider the balanced chemical equation for the reaction. The reaction is as follows:

CH2Cl2 + Cl2 -> CHCl3 + HCl

From the equation, we can see that one mole of dichloromethane (CH2Cl2) reacts with one mole of chlorine (Cl2) to produce one mole of chloroform (CHCl3) and one mole of hydrogen chloride (HCl).

To calculate the mass of chlorine required, we need to know the molar mass of chloroform and dichloromethane. The molar mass of chloroform (CHCl3) is approximately 119.38 g/mol, and the molar mass of dichloromethane (CH2Cl2) is approximately 84.93 g/mol.

Now, let's calculate the mass of chlorine required:

1. Calculate the number of moles of chloroform: - Mass of chloroform (CHCl3) = 243 kg = 243,000 g - Number of moles of chloroform = Mass of chloroform / Molar mass of chloroform - Number of moles of chloroform = 243,000 g / 119.38 g/mol

2. Calculate the number of moles of dichloromethane: - Since the reaction is 1:1 between dichloromethane and chloroform, the number of moles of dichloromethane is the same as the number of moles of chloroform.

3. Calculate the mass of chlorine: - Number of moles of chlorine = Number of moles of dichloromethane - Mass of chlorine = Number of moles of chlorine * Molar mass of chlorine

Let's perform the calculations:

1. Number of moles of chloroform: - Number of moles of chloroform = 243,000 g / 119.38 g/mol

2. Number of moles of dichloromethane: - Number of moles of dichloromethane = Number of moles of chloroform

3. Mass of chlorine: - Mass of chlorine = Number of moles of chlorine * Molar mass of chlorine

To find the molar mass of chlorine, we can refer to the periodic table. The molar mass of chlorine (Cl2) is approximately 70.90 g/mol.

Let's calculate the mass of chlorine:

1. Number of moles of chloroform: - Number of moles of chloroform = 243,000 g / 119.38 g/mol

2. Number of moles of dichloromethane: - Number of moles of dichloromethane = Number of moles of chloroform

3. Mass of chlorine: - Mass of chlorine = Number of moles of chlorine * Molar mass of chlorine

Now, let's calculate the mass of chlorine:

1. Number of moles of chloroform: - Number of moles of chloroform = 243,000 g / 119.38 g/mol
