Answer : The number of carbon atoms present in isopropyl alcohol is,
Solution : Given,
Mass of isopropyl alcohol = 25 g
Molar mass of isopropyl alcohol = 60 g/mole
In isopropyl alcohol molecule, there are 3 carbon atoms and 8 hydrogen atoms and 1 oxygen atom present.
First we have to calculate the moles of isopropyl alcohol.
As we know that 1 mole of gas contains number of atoms
As, 1 mole of gas contains number of carbon atoms
So, 0.416 mole of gas contains number of carbon atoms
Therefore, the number of carbon atoms present in isopropyl alcohol is,
