Well, you start by obtaining the molecular weight and density of each. They are:
Chloroform MW =119.38 g/mol; Density = 1.48 g/mL
Water MW = 18.0153 g/mol; Density = 1.00 g/mL
Then pick a volume of water to begin with. For simplicity, let's say 18.0153 mL (1 mole) of H2). Since 100 ppm means that there is 1 molecule of chloroform for every 10,000 molecules of water that means we need 1/10000th of a mole of chloroform. So just divide 119.38 grams/mole molecular weight by 10000 and we get 1.1938 x 10-3 grams. Now just divide the grams by the density 1.1938 x 10-3 g / 1.48 g*mL-1 = 8.07 x 10-4 mL or 0.807 microliters.
Practical procedure:
18.0153 mL goes into 100 mL about 5.551 times.
Since the amount of chloroform is so small we can simply add 8.07 x 10-4 mL x 5.551 = 4.48 microliters to a 100 mL volumetric flask then fill to the line with water and that should give you very very near 100 ppm chloroform water solution.
What else can I help you with?
The normal boiling point of chloroform which has a higher vapor pressure than water at 100 degrees celsius is?
Chloroform has a normal boiling point of 61.2 degrees Celsius, which is lower than the boiling point of water. This means that chloroform will have a higher vapor pressure than water at 100 degrees Celsius, where water is at its boiling point but chloroform is not.
What is the normal boiling point of the chloroform which has a higher vapor pressure than water at 100 Celsius is?
The normal boiling point of chloroform is approximately 61.2°C. Since chloroform has a higher vapor pressure than water at 100°C, it means chloroform will boil first before water at that temperature, due to its lower boiling point.
What is Double strength chloroform water?
the concentrated chloroform water is called double strength chloroform water it is prepared by adding 5ml conc.chloroform to the 100 ml of water
Would chloroform float on water?
Chloroform is denser than water and would not float on its surface. Chloroform has a density of about 1.48 g/cm3, while water has a density of 1g/cm3. When added to water, chloroform would sink and form a separate layer at the bottom.
How do you calculate chloroform concentration?
To calculate chloroform concentration, divide the mass or volume of chloroform by the total volume of the solution it is in. For example, if you have 5 grams of chloroform in 100 mL of solution, the concentration would be 5 grams / 100 mL = 0.05 g/mL or 50 mg/mL.

The normal boiling point of chloroform which has a higher vapor pressure than water at 100 and degC is?
The boiling point of chloroform is 61,15 oC.
Would chloroform float on water?
Chloroform is denser than water and would not float on its surface. Chloroform has a density of about 1.48 g/cm3, while water has a density of 1g/cm3. When added to water, chloroform would sink and form a separate layer at the bottom.
How much 25 mg by ml solution can you make by diluting 120 ml of a 100 mg by ml solution?
480ml
How do you calculate chloroform concentration?
To calculate chloroform concentration, divide the mass or volume of chloroform by the total volume of the solution it is in. For example, if you have 5 grams of chloroform in 100 mL of solution, the concentration would be 5 grams / 100 mL = 0.05 g/mL or 50 mg/mL.
What is the chemical composition of RBC diluting fluid?
RBC diluting fluid commonly consists of an isotonic saline solution containing electrolytes and buffers to maintain the stability of red blood cells during counting. The composition may vary based on the specific laboratory protocol or commercial product used.
Can you drink 100 proof vodka without diluting?
It depends from person to person .
Can we make 1N NaOH solution from 0.1N NaOH solution?
Yes, you can make a 1N NaOH solution from a 0.1N NaOH solution by diluting it 10 times. For example, to make 1 liter of 1N NaOH solution, you would mix 100 ml of the 0.1N NaOH solution with 900 ml of water.

How do you calculate the Percent composition by mass of chloroform?
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.
