Question
Solve problem:
In two moles of acetaldehyde (CH3CHO) calculate the number of molecules of acetaldehyde
Solution
Molecular formula of acetaldehyde: C2H4O
Moles of acetaldehyde = 2 mol
Number of molecules of acetaldehyde = Moles of acetaldehyde × Avogadro number
= 2 mol × 6.022 × 1023 molecules/mol
= 12.044 × 1023 molecules of acetaldehyde
Number of molecules of acetaldehyde = 12.044 × 1023
