Answer 2

For a: The number of moles of carbon are 4 moles

For b: The number of moles of hydrogen are 8 moles

For c: The number of moles of oxygen are 2 moles

For d: The number of molecules of acetaldehyde present are $1.2044\times 10^{24}$

Explanation:

The chemical formula for acetaldehyde is $CH_3CHO$

This is made by the combination of 2 moles of carbon atoms, 4 moles of hydrogen atoms and 1 mole of oxygen atoms

We are given:

Moles of acetaldehyde = 2 moles

• For a:

Number of moles of carbon = (2 × 2) = 4 moles

• For b:

Number of moles of hydrogen = (4 × 2) = 8 moles

• For c:

Number of moles of oxygen = (1 × 2) = 2 moles

• For d:

According to mole concept:

1 mole of a compound contains $6.022\times 10^{23}$ numer of molecules

So, 2 moles of acetaldehyde will contain = $(2\times 6.022\times 10^{23})=1.2044\times 10^{24}$ number of molecules
