ethyl is C2H5 and propyl is C3H7 and cyclobutane is C4H8 so removing two hydrogens that will be replaced by the ethyl and propyl leaves (C2H5)(C3H7)C4H6 which leaves a net C9H18
What is the molecular formula of 2-Butyne
Ch2(cho)2 is the molecular formula for malondialdehyde.
92
C2H4O2=molecular formula, basically you multiply the empirical formula by 2.
C4H6. C2H3 gives a molecular mass of 27, 54/27 gives 2. Therefore the molecular formula is twice the empirical formula.
If C2H5 was the molecular formula its molecular mass would be 29 ( 12 x 2 + 5 x 1) However, 29 x 2 = 58 the actual molecular mass. So we double up the atoms in C2H5 to C4H10 . C4H10 is the molecular formula.
The mass would be approximately 92 grams.

Empirical formula = C3H5O Molar mass of empirical formula = 3(12.01)+5(1.008)+1(16) = 57.07 Molar mass of molecular fomula = 114.15 n = Molar mass of molecular fomula/Molar mass of empirical formula = 114.15/57.07 n = 2 Molecular formula = n(empirical formula) Molecular formula = 2(C3H5O) = C6H10O2 Check: 6(12.01)+10(1.008)+2(16)= 114.14
