what is the molecular formula for a compound, having a empirical formula of CH20 and a molar mass of 150 g/mol
1 answer:
The molecular formula is C₅H₁₀O₅.
EF = CH₂O
EF Mass = (12.01 + 2.016 + 16.00) u = 30.03 u
MF mass = 150 u
MF = (EF)_<em>n
</em>
<em>n</em> = MF Mass/EF Mass = 150 u/30.03 u = 4.995 ≈ 5
MF = (CH₂O)₅ = C₅H₁₀O₅
