At Grangemouth, BP make large quantities of ethanol by a process called catalytic
hydration of ethene:
C2H4 + H2O → C2H5OH
What mass of ethanol would be produced from 560kg of ethene
process step by step, please

Answer:

Mass =  799971.50 g

Explanation:

Given data:

Mass of ethene = 560 Kg (560 Kg ×1000 g/1 Kg= 560000 g)

Mass of ethanol produced = ?

Solution:

Chemical equation:

C₂H₄ + H₂O      →     C₂H₅OH

Number of moles of ethene:

Number of moles = mass/molar mass

Number of moles = 560000 g / 28.05 g/mol

Number of moles = 19964.35 mol

Now we will compare the moles of ethene and ethanol.

            C₂H₄        :         C₂H₅OH

               1            :            1

       19964.35      :         19964.35

Mass of ethanol:

Mass = number of moles × molar mass

Mass =  19964.35 mol × 46.07 g/mol

Mass =  799971.50 g
