How many moles are there in 4.00 g of ethanol, ch 3ch 2oh?

Explanation:

Number of moles present in a substance is equal to the mass divided by molar mass.

Mathematically,      No. of moles =

As it is given that mass is 4.00 g and molar mass of is 46.07 g/mol.

Hence, calculate the number of moles of as follows.

                 No. of moles =

                                       =

                                       = 0.086 mol

Thus, we can conclude that number of moles of present in 4.00 g is 0.086 mol.
