    Answer:chemical formula of acetic acid is  or

    so, molecular mass of acetic acid = 2 × atomic mass of C + 4 × atomic mass of H + 2 × atomic mass of O

    = 2 × 12 + 4 × 1 + 2 × 16

    = 24 + 4 + 32

    = 60g/mol

    given mass of acetic acid = 22g

    so, no of moles of acetic acid = given mass/molecular mass

    = 22/60 ≈ 0.367

    so, number of moles of acetic acid is 0.367mol

    number of molecules in 0.367 mol of acetic acid = 6.022 × 10²³ × 0.367

    = 2.21 × 10²³
