C2h6o how many moles of ethanol are present in a 10.0 g sample of ethanol

Explanation:

It is known that number of moles is equal to mass divided by molar mass of the compound or substance.

Mathematically,   No. of moles =

Since, it is given that mass is 10 g and molar mass of ethanol is 46.07 g/mol.

Hence, calculate the number of moles of ethanol as follows.

          No. of moles =

                                =

                                = 0.217 mol

Thus, we can conclude that there are 0.217 moles of ethanol are present in a 10.0 g sample of ethanol.

the reaction mixture contains some ammonia, plus a lot of unreacted nitrogen and hydrogen. the mixture is cooled and compressed, causing the ammonia gas to condense into a liquid. the liquefied ammonia is separated and removed. the unreacted nitrogen and hydrogen are then recycled back into the reactor .
