Question

Give the values for the following,

Gram atom of Potassium = ____ g of Potassium?

Answer 1

• One mole of a substance is the measure of the amount of that substance.
• It is equal to the number of atoms present in 12 grams of the carbon-12 isotope.
• The gram atomic mass or molar mass is defined as the atomic mass of a mole of an element expressed in grams.
• The molar mass of an element = 1 mole of that element = 6.022×10²³ atoms.
• 1g atom is the gram atomic weight of the element = atomic weight of the element in grams.

Therefore Gram atom of Potassium = atomic weight of potassium= 39g

Gram atom of potassium= 39 g of potassium.
