If a compound has a molar mass of 180 g/mol and its empirical formula is CH2O, what is its molecular formula? CH2O C2H4O2 C6H12O
2 answers:
Its molecular formula : C₆H₁₂O₆
<h3>Further explanation </h3>The empirical formula(EF) is the smallest comparison of atoms of compound forming elements.
A molecular formula(MF) is a formula that shows the number of atomic elements that make up a compound.
(EF) n = MF
its empirical formula is CH₂O
CH₂O : 12+2+16=30

Answer:
Au
Explanation:
For the density of a face-centered cubic:
where
= molar mass of the compound
avogadro's constant
the volume of a unit cell
Given that:
Density = 19.30 g/cm³
a = 0.408 nm
a =
a =
∴
Thus, the molar mass of 197.37 g/mol element is Gold (Au).
