I. Calculate the number of moles and molecules of acetic acid present in 22 g of it.
To find : the number of moles and molecules present in 22 g of acetic acid
molecular mass of CH3COOH =(2×atomic mass of C)+(4× atomic mass of H)+(2×atomic mass of O)
Number of moles =\(mass\over molar \space mass\)
Number of molecules = Number of moles × Avogadro's constant
=0.3667 × 6.022×1023 molecules
