What is the mass in grams of 9.06 x 10^24 molecules of methanol (ch3oh)?

Explanation:

As we know that according to Avogadro, 1 mole of an atom contains atoms.

So, number of atoms given in the methanol are . Hence, calculate the number of moles present as follows.

   No. of moles =

                         = 15.04 mol    

As molar mass of methanol is 32.04 g/mol. Hence, the mass of given methanol is as follows.

          No. of moles =

               15.04 mol =

             mass = 481.28 g

Thus, we can conclude that mass of molecules of methanol () is 481.28 g.

i have a feeling this is a gay person trolling to make straights look bad.

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.
