C2H4O is the formula of acetaldehyde and CH2O is the chemical formula of formaldehyde.
A.I think you are asking for acetaldehyde.
so we will start from C2H4O.
In one mole of any substance there are 6.023×10^23 particles. There are two carbon atoms in one molecule of acetaldehyde it means there are 2×6.023×10^23 particles of carbon in one mole of acetaldehyde ,but the question is about two moles that's why we'll take the same number of carbon atoms two times like =2×6.023×10^23+2×6.023×10^23
=12.046×10^23+12.046×10^23
=24.092×10^23 Carbon atoms in two moles of acetaldehyde.
Or you can say simple that two moles of carbon atoms are there in one mole of acetaldehyde so there will be four moles of carbon atoms in two moles of acetaldehyde.
B.There are four hydrogen atoms in one molecule of acetaldehyde. It means there are four moles of hydrogen atom in one mole of acetaldehyde. If there are four moles in one mole then there will be 4+4=8 moles of hydrogen atoms in two moles of acetaldehyde.
C.There is one oxygen atom in one molecule of acetaldehyde. similarly one mole of oxygen atoms in one mole of acetaldehyde. In two moles of acetaldehyde two moles of oxygen atoms.
D.There are 6.023×10^23 molecules in one mole so 2×6.023×10^23=12.046×10^23 molecules of acetaldehyde in two moles of acetaldehyde.
Thank you.
