What is the difference between molecular and formula weights?
The formula mass (formula weight) of a molecule is the sum of the atomic weights of the atoms in its empirical formula. The molecular mass (molecular weight) of a molecule is its average mass as calculated by adding together the atomic weights of the atoms in the molecular formula.
How many grams are in 1 mol of ZnS?
You know that zinc sulfide has a molar mass of 97.474 g mol−1 , which basically means that 1 mole of zinc sulfide has a mass of 97.474 g .
What is the formula of ZnS?
ZnSZinc sulfide / Formula
Formula and structure: The chemical formula of zinc sulfide is ZnS, and its molar mass is 97.47 g/mol.
What type of reaction is zinc sulfide?
Zn (s) + S (s) → ZnS (s) When the mixture is touched with a heated metal rod, however, a violent reaction occurs (the reaction is termed exothermic; producing heat) and zinc sulfide is formed as the product.
What kind of solid is ZnS?
ZnS is a / an ionic ionic crystal.
What is the difference between formula and molecular formula?
What is the difference between molecular formula and structural formula? The molecular formula is just the elements of the molecules with the number of elements. The structural formula is drawing the structure of the molecule.
How is formula unit mass different from molecular mass?
Formula mass is defined as the sum of atomic masses of the ions present in the formula unit of an ionic compound whereas molecular mass is the sum of the atomic masses of the atoms in a molecule.

Is zinc sulfide ionic or molecular?
Answer and Explanation: ZnS (zinc sulfide) is an ionic compound. This is because ionic compounds are made of metals and nonmetals.
Why is ZnS white?
As the size of the cation increases, upon moving down in the periodic table, the overlap between the orbitals decreases and the band gap shifts to lower energy. Since, the band gap decreases from ZnS to HgS, the colour of ZnS is white, CdS is yellow and HgS is black.

How do you find the weight of a chemical compound?
Browse the list of common chemical compounds. In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together.
