Can a compounds molecular formula be 2.5 times greater than the empirical formula?

No. It must be a whole number.
Since the empirical formula of a compound shows the proportions of the elements in the simplest whole number ratio there is going to be at least one odd number in the formula. Multiplying by 2.5 would then result in you having half an atom somewhere in the molecule, which you can't really have.

Which compound is more like an ionic compound NH3 or PH3?
No. They are covalent/molecular compounds.
Which isotopes has the greater natural abundance in antimony?
Antimony (121.90) has the greater abundance, Because its molecular mass is closer to that of Antimony which is(121.75)
How are properties of an ionic compound different from a covalent compound?
An ionic compound has an electronegativity difference greater than 1.7 between molecules (or poly-atomic ions). as covalent bonds are less than 1.7 in electronegativity difference. also, ionic compounds consist a metal and a non-metal.
What properties can be used to form ionic compounds?
electronegativity. the greater the difference in electronegativity of the elements the greater the likelihood of them forming ionic bonds.
How does the total number of elements compare to the total number of compounds?
There are a bit more than 100 elements however there are far, far more than 100 millions compounds, each day more compounds are produced, there are a lot of compounds with unknown structure, not having official names. So the ratio is much bigger than 1 to a million
Is the number of atoms in a molecular formula always greater than a empirical?
No. A molecular formula can be the same as the empirical formula, such as CH4 (methane), because the two component atoms exist in a ratio that cannot be mathematically further broken down - one carbon to four hydrogens. In this case the molecular formula (the actual number of atoms per molecule), and the empirical formula (the simplest ratio of those numbers) is identical. On the other hand, ethane, C2H6 - two carbons to 6 hydrogens - has a molecular formula of C2H6 and a empirical formula of CH3, the ratio of 2 to 6 reduced to its simplest whole number form. Sooooooooooo, the molecular formula will always be equal to or greater than the empirical formula, and the empirical formula will always be equal to or less than the molecular formula. In other words (as if that wasn't enough), the molecular formula will never be less than the empirical formula and the empirical formula will never be greater than the molecular formula, but THE TWO CAN BE EQUAL. Whew!!! Ray
Which compound is more like an ionic compound NH3 or PH3?
No. They are covalent/molecular compounds.
What is fructose solution?
fructose has same molecular formula but different structural formula. but the amount of sweetness of fructose is much much greater than glucose or sucrose. so the fructose solution is the sweetest solution...
What molecule is larger glucose or sodium chloride?
Wate is molecular , H2O. NaCl is giant ionic laattice and is not molecular when normally encountered. In terms of mass the formula unit of NaCl is greater than than the molecular mass of water.
Does oxygen have a greater mass than chlorine?
Atomic oxygen does not have a greater atomic mass than chlorine, nor does molecular oxygen. The atomic mass of chlorine is approximately 35 g/mol, while molecular (O2) oxygen has a molecular mass of 32 g/mol.
Is molecule movement is greastest a solid?
Molecular movement in a solid is very minimal. Molecular movement in liquids and gases are greater than in a solid.
What has more mass water or sulfuric acid?
The molecular maass of sulfuric acid (98,08) is greater than the molecular mass of water (18).

Can ionic compounds dessolve in water?
Ionic compounds can only be dissolved in water if the energy of hydration is greater than latice energy of that compound
What properties can be used to form ionic compounds?
electronegativity. the greater the difference in electronegativity of the elements the greater the likelihood of them forming ionic bonds.
Can the arrow in chemical equation indicate which compounds have greater mass?
No, the arrow indicates which way the reaction proceeds, often with 2 arrows being used pointing in both directions indicating the reaction is in equilibrium. The compound's mass can be calculated using the molecular mass of the compound from the periodic table.
