WebThe value given 6.022 x 10 23 is called Avagadro's number for the scientist that found the number of atoms in 12 grams of carbon 12. Why use 12 grams? This is the theoretical atomic mass of the Carbon-12 isotope (6 protons and 6 neutrons). This means that the atomic mass or atomic weight (12 grams) of carbon is equal to exactly 1 mole of carbon.

Ch4 Molar Mass - QnA
WebExplanation: The molar mass of methane (CH4) is calculated by adding the molar masses of each individual atom in the molecule. 1 mole of Carbon atoms has a molar mass of 12.01 g/mol. 4 moles of Hydrogen atoms have a molar mass of 4.00 g/mol. Therefore, the molar mass of CH4 is 12.01 g/mol + 4.00 g/mol = 16.01 g/mol. Webthe A r (relative atomic mass) or M r (relative formula mass) ... Calculate the maximum mass of carbon dioxide that can be produced.
