The molar mass of Cadmium is 112.41 grams, so first you need to convert your given value to moles. To do that divide 3 grams by the molar mass of 112.41 grams. That gives you an answer of .0267 moles of cadmium. Then to convert that value to atoms, you must use the constant of 6.022X10^23 atoms in one mole. Multiply the moles by that number, which will give you a final answer of (1.61X10^22) atoms in 3 grams of cadmium.

Hope this helps!

  • Metals: magnesium and sodium.
  • Nonmetals: fluorine, chlorine, bromine, sulfur and nitrogen.
  • Metalloids: silicon and tellurium.
  • Noble gases: helium.

Metals: They occupy the left and central areas of the Periodic Table; therefore, they constitute a majority group of the elements.

Nonmetals: They are located in the upper right region of the Periodic Table.

Within the Periodic Table, the metalloids lie diagonally from boron to polonium. Items above on the right are nonmetals, and items below on the left are metals.

The noble gases are located in group 18 of the Periodic Table.

Explanation:The coefficient are as follows: 2: 6: 4: 4

Each atom on the reactant and product side are equal.

Reactant Product

C 2x2 = 4 4x1 = 4

H 2x4 = 8 4x2 = 8

O 6x2 = 12 (4x2) + 4 = 12
