M is an organic acid with vapour density 75. Percentage composition is C=32% and O=64%. Determine the molecular formula of M acid
Vapour density =75 therefore Molar mass of acid = 75*2now it is given it contains 32 %C64% Oand 4% h we can consider it as in 100 gram of this acid 32 gram is C 64 gram is O and 4 gram is H now using unitary methode since 100 gram contain 32 gram C ------>1 gram contain gram Cand gram conatin =48gram there fore 4 moles of carbon simillarly 150*64/100=96 ====6 moles O and 6 gram h now the acis id C4 O6 H6
