Achemist needs 22.0 grams of phenol, c6h5oh, for an experiment. how many molecules of phenol would this be?

The number of molecules would be - 1.410* molecules in 22 grams of phenols.

The molecular formula of Phenol is C6H5OH

, Therefore, molecular weight:

= 6(Mass of carbon) + 6(Mass of hydrogen) + 1 (Mass of oxygen)

= 6 × 12.0107 + 6 × 1.00784 + 15.999 × 1

= 94.11

=> The number of moles of phenols:

=> No of mol of phenol = weight/Mwt

= 0.234 moles

=> The number of molecules of phenol would be in 22 grams:

molecules =

Thus, the number of molecules would be - 1.410 molecules.
