A dipole moment is defined as a measure of the molecular polarity of a compound; the magnitude of the partial charges on the ends of a molecule times the distance between them (in meters). In order for there to be a dipole moment the element must must have molecular polarity which results from molecules with a net imbalance of charge (often a result of differences in electronegativity). If the molecule has more than two atoms, both shape and bond polarity determines the molecular polarity. In general look for a difference in electronegativity of the elements of a molecule which results in polarity and thus a possible dipole moment. Note that molecular shape influence polarity so molecules with the same elements but a different shape (and vice versa) won't have the same dipole moment.

How do you find the molecular formula for a compound with mass of 78amu?

You can't without more information. You cannot go from the molecular weight of a compound to its formula without more information about what atoms it contains.See the Related Questions link to the left for a more detailed discussion of this.


A compound has a mass of 16.7g 12.7g Iodine 4g Oxygen Therefore the empirical formula is I2O5 What additional information do you need to work out the molecular formula?

To determine the molecular formula, you would need the molar mass of the compound. With the molar mass, you can calculate the empirical formula mass and then determine the ratio between the empirical formula mass and the molar mass to find the molecular formula.


What do you know about chemical compound by looking at it's chemical formula?

the number and kinds of atoms in the compoundIn an ionic compound, the formula gives the ions and their ratios in the crystal lattice. In a molecular compound, the formula gives the numbers of atoms of each element in a molecule.


How the moleculer formula of a compound is calculated if its emperical formula is known?

The gram molecular mass of the molecule must be measured by some independent method such as freezing point depression or boiling point elevation. Then the factor by which to multiply all of the subscripts in the empirical formula to get the molecular formula is the closest integer to the ratio of gram molecular mass to the gram molecular mass of a single unit of the empirical formula.

The molecular mass of the compound is 132 amu. What is the molecular formula?

To determine the molecular formula of a compound with a molecular mass of 132 amu, you would need additional information such as the elements present in the compound and their respective atomic masses. Without this information, it is not possible to determine the molecular formula.


How do you find molecular fomula?

To find the molecular formula of a compound, you need to know its empirical formula and molar mass. Divide the molar mass of the compound by the molar mass of the empirical formula to find the "multiplication factor." Multiply the subscripts in the empirical formula by this factor to get the molecular formula.


What are similarities between molecular formula and empirical formula of a compound?

Both formula helps us to know what types of molecules are involved in the compound


What critical piece of information must be known in order to determine the molecular formula?

To determine the molecular formula of a compound, one must know its molar mass. This information, coupled with the molecular weight of its individual elements, allows for the calculation of the ratio of atoms present in the compound, and subsequently leading to the determination of its molecular formula.


What is the number of apples in 0.25 moles of apples?

The question does not contain enough information. The equation is number of moles = mass (of compound) / molecular mass of compound. You do not know the weight of an apple (cannot get one specific figure for this), nor does an apple have a molecular weight

How do you know a compound is ionic or molecular?

An ionic compound is a pure substance that is formed from a metal and a nonmetal. It has a fairly high melting point and is a conductor of electricity when in a molten or aqueous state . A molecular compound, on the other hand, is a pure substance that is formed from nonmetals. It has a fairly low melting point, and cannot conduct electricity regardless of state. Another important difference between the two is that an ionic compound is a crystalline solid at standard ambient temperature and pressure (SATP), whereas a molecular compound can be in a solid, gas or liquid state at SATP.

Is As4O6 ionic or molecular?

Oh, dude, As4O6 is a molecular compound. I mean, it's got arsenic and oxygen hanging out together, but they're not really into that whole ionic bonding thing, you know? They're just chilling and sharing electrons in a cozy little molecular arrangement. So yeah, it's all molecular and stuff.
