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.
Yes, you definitely need to know the molecular weight of a compound to calculate molarity.
You need to know the Relative Molecular Mass of the compound, then you find the ratio of that compared to the R.M.M. of I2O5 and then multiply the ratio by I2O5. That should be it.
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.
I don't know absolutely for certain but chocolate is an organic compound which probably means it has covalent bonding. Also is melts at a low temperature and forms a suspension in water which are characteristics of a simple molecular structure which would mean it is not ionic. No I don't think chocolate is an ionic compound.
By determining the molecular mass, then dividing the molecular mass by the formula mass of the empirical formula to determine by what integer the subscripts in the empirical formula must be multiplied to produce the molecular formula with the experimentally determined molecular mass.
This is impossible. In order to find this you must know the elements in the compound
Both formula helps us to know what types of molecules are involved in the compound
Yes, you definitely need to know the molecular weight of a compound to calculate molarity.
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

X is not an electrolyte, since you know that it isn't an acid. molecular compounds can be both soluble and insoluble.
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.
- measuring the mass of this compound and the volume (or mass) of the solution - by chemical analysis (and determination of the concentration of this compound) If you know the molarity, multiply moles by molecular weight and adjust per the volume you have. If you don't know the molarity, a simple means is to just evaporate the solvent and weigh the remaining compound
