Final answer:
The mass of the trifluoroacetic acid sample can be calculated using the formula: Mass of trifluoroacetic acid = molarity of trifluoroacetic acid x molar mass of trifluoroacetic acid.
Step-by-step explanation:
The mass of the trifluoroacetic acid sample can be calculated using the formula:
Mass of trifluoroacetic acid = molarity of trifluoroacetic acid x molar mass of trifluoroacetic acid
First, you need to find the molar mass of trifluoroacetic acid, which is equal to the sum of the molar masses of its constituent elements. The molar mass of fluorine (F) is approximately 19.00 g/mol, and the molar mass of chlorine (Cl) is approximately 35.45 g/mol.
Therefore, the molar mass of trifluoroacetic acid is:
Molar mass of trifluoroacetic acid = (3 x molar mass of fluorine) + molar mass of carbon + (2 x molar mass of oxygen)
Once you have the molar mass, you can use the given molarity (x = 0.0107855M) to calculate the mass of the trifluoroacetic acid sample.
