How do you calculate molar mass for covalent molecules and for ionic compounds? explain.

See the explanation and examples below, please.

Explanation:

To calculate the molar mass of a substance you must have the atomic weights of each component:

Example NaCl ionic compound (sodium chloride, known as table salt)

Molar mass NaCl = Atomic weight Na + Atomic weight Cl = 22, 98 gr + 35, 45gr = 58.35 grams / mol

Example covalent compound HCl (hydrochloric acid) = Atomic weight H + Atomic weight Cl = 1, 004gr + 35, 45 gr = 36, 45 grams / mol

In the case of having compound H20 (water), it is calculated:

Molar mass NaCl = 2 x (Atomic weight H) + Atomic weight 0 (the atomic weight of 1 mol of Hydrogen is multiplied by 2)

The molecular mass of an ionic or a covalent chemical compound is the weight of the specimen measured by sum of the substance in present in that compound.

Explanation:

The low and medium molecular weight can be used to evaluate the structure of components of the atom, as determined by mass spectrometry. The molecular masses of macro molecules, such as proteins, may also be measured by mass spectrometry however, if crystallographic or mass spectrometric information is not sufficient, methods focused on viscosity and light-scattering are also used to assess molecular mass

beta decay is the answer

sorry i was late, but i don't know what assignment your talking about, i'm in flvs as well, im in earth space science. but u are behind pace bc every class should be in the 3's or 4'
