Question

calculate the mass of 1g of CO2​

Answer 1

Answer:

practical chemical unit for handling atoms and molecules. Since atoms and molecules are so small, it is impossible to handle and count atoms and molecules individually. Therefore, the Chemists devised a special unit to describe very large number of atoms, ions and molecules and it is called mole and is abbreviated as mol.

A mole can be defined as “the molecular mass, atomic mass and formula mass of a substance expressed in grams

Carbon dioxide contain one carbon and two oxygen atoms and

Mass of one Carbon mole = 12 g

Mass of one Oxygen mole = 16 g

Mass of two Oxygen mole = 2 x 16 = 32 g
