1) Get the chemical formula to determine the number of each type of atom present in the compound.
2) Multiply the atomic weight (get it from the Periodic Table) of each element by the number of atoms of that element present your specific compound
3) Do the Sum in unit grams/mole
NaCl
(1x23 grams/mole Na) + (1x 35.5 grams/mole Cl) = 58.5 grams/mole NaCl
Multiply the number of moles times the molar mass of the compound. Moles cancel and you are left with mass in grams.For example: What is the mass of 2.47 moles of sodium chloride, NaCl?Known: The molar mass of NaCl is 58.44g/mol. (Using atomic weights in grams from the periodic table.)Solution:2.47mol NaCl x 58.44g/mol NaCl = 144g NaCl
The word you want is: heterogeneous, but I have no idea how it relates to the periodic table!

Some elements in the periodic table have a nucleus that is surrounded by a cloud of electrons with a negative charge. This is one sentence using nucleus and periodic table.

No.
You use the prefix of the words to write the formula for a covalent compound, example "di-" is the prefix and it is 2.
Dmitri Mendeleev made the periodic table. He is credited as being the creator of the first version of the periodic table of elements. Using the table, he predicted the properties of elements yet to be discovered.
It is an element. It appears in the periodic table with atomic number 92. It cannot be broken down into simpler substances using chemical means.
Dmitri Mendeleev is credited with the publication of the first widely recognized periodic table.

The Modern Periodic Table is useful because using the symbols are much easier than writing out the whole word.
