What is the molecular formula of a compound with the empirical formula P2O5 and a gram molecular mass of 284 grams?
The chemical formula of this compound is P4O10. However, it is named after its empirical formula, which is P2O5. The molar mass of phosphorus pentoxide corresponds to 283.9 g/mol.
Which molecule has a trigonal planar shape because it does not have any lone pair of electrons on the central atom?
Boron trifluoride bonding. The geometry of the BF3 molecule is called trigonal planar (see Figure below). The fluorine atoms are positioned at the vertices of an equilateral triangle. The F-B-F angle is 120° and all four atoms lie in the same plane.
Which formula is both molecular and an empirical formula?
Both have the same empirical formula, yet they are different compounds with different molecular formulas. Butene is C4H8, or four times the empirical formula; ethylene is C2H4, or twice the empirical formula….
| Empirical formula | CH (92.2% C; 7.8% H) |
|---|---|
| Compound | acetylene |

Is p2o5 an empirical formula or molecular formula?
P₂O₅
Phosphorus pentoxide/Formula
What is the reason there is a bent molecular geometry in molecules?
In the case of bent molecules, that shape is always between 109.5 and 104 degrees. Bent molecules occur most frequently in group 16 elements because they have 6 electrons in their outer shell, allowing for 2 bonds and 2 lone pairs.
What is the bond angle of a trigonal planar molecule?
120°
Trigonal planar: triangular and in one plane, with bond angles of 120°.
