Using the periodic table to find the molar mass of each of the following elements.

  • Sodium (Na): 22.99  g/mol
  • Oxygen (O): 16.00  g/mol
  • Carbon (C): 12.01   g/mol

The molar mass of a chemical compound is defined as the mass of a sample of that compound divided by the amount of substance in that sample.

  • The molar mass of an element is the mass in grams of one mole (6.02 x 1023 particles) of the element.

M = m / n

here,

M = molar mass

m = mass of a substance (in grams)

n = number of moles of a substance

  • the molar mass of an element is simply the atomic mass in g/mol
  • The Molar Mass of an atom corresponds directly with its atomic mass on the periodic table.
  • in the periodic table, we can find the atomic number and atomic mass

Sodium (Na)

  • the atomic number from the periodic table is 11
  • the molar mass of sodium is almost twice which is also present in table

= 22.99

similarly,

Oxygen (O)

  • the atomic number from the periodic table is 8
  • the molar mass of oxygen

= 16 gram

Carbon (C)

  • the atomic number from the periodic table is 6
  • the molar mass of oxygen

= 12.01

Using the periodic table to find the molar mass of each of the following elements:

  • Sodium (Na): 22.99  g/mol
  • Oxygen (O): 16.00  g/mol
  • Carbon (C): 12.01   g/mol
