Final answer:
To find the number of molecules of N(CF₃)₂CFCF₂ in 532 grams of the substance, calculate the molar mass, determine the number of moles, and convert to molecules using Avogadro's number.
Step-by-step explanation:
To find the number of molecules of N(CF₃)₂CFCF₂ in 532 grams of the substance, we need to use the concept of molar mass and Avogadro's number. First, we calculate the molar mass of N(CF₃)₂CFCF₂ by adding up the atomic masses of all the atoms in the compound.
Then, we calculate the number of moles of N(CF₃)₂CFCF₂ in 532 grams using the formula: Moles = Mass / Molar Mass. Finally, we convert the number of moles to molecules using Avogadro's number, which states that 1 mole of a substance contains 6.022 x 10^23 molecules.
Therefore, the number of molecules of N(CF₃)₂CFCF₂ in 532 grams of the substance would be:
Moles = 532 g / Molar Mass
Number of Molecules = Moles x Avogadro's number
