The mass number of an element is equal to the sum of the elements neutrons and protons.
In this case, the equation is balanced.
1 mole of any substance contains approximately 6.022 x 10^23 atoms. This number is known as Avogadro's number and represents a mole of particles in a substance.
A balanced chemical equation is one in which the number of atoms of each element is the same on both the reactant and product sides of the equation. This ensures that the law of conservation of mass is obeyed.
Matter is not created nor destroyed in chemical reactions, the total mass and number of atoms before the reaction equals the total number of atoms and mass after the reaction. Conservation of mass law.
To calculate the number of moles from the number of atoms, you can use Avogadro's number, which is approximately 6.022 x 10^23 atoms per mole. Divide the number of atoms by Avogadro's number to find the number of moles.
In this case, the equation is balanced.
In this case, the equation is balanced.
The total number of protons and neutrons in an atoms nucleus. The proton number on the other hand states just the number of protons in an atoms nucleus, hence the atomic number take away the proton number equals the number of neutrons in an atoms nucleus.
The number of hydrogens equals 2x the number of carbon atoms, plus 2 extra hydrogens.
1 mole equals an Avagadro number of particles = 6.022 x 1023 so5.1 x 1021 /6.022 x 1023 = 8.469 x 10-3

some atoms are heavier than others as they have higher relative Atomic Mass, by which is equals to proton number + number of neutrons in an atom, according to the Periodic Table of the elements
