Atomic Mass is the sum of the protons and neutrons in the nucleus. It also takes Isotopes into consideration in an amount that is dependent on their frequency in nature.
Eg. Carbon 12 is normal(6 protons, 6 neutrons), but carbon 13 and 14 have 1 and 2 additional neutrons, respectively. Their frequency in nature is what factors them into the atomic mass on a Periodic Table.

What is a balanced equation for charge and mass?
A balanced equation for charge and mass ensures that the total charge and mass are conserved in a chemical reaction. This means that the sum of the charges and the sum of the masses of the reactants must equal the sum of the charges and masses of the products. In a chemical equation, this is represented by having equal numbers of each type of atom and matching charges on both sides of the equation. For example, in the reaction of hydrogen and oxygen to form water, the balanced equation is 2H₂ + O₂ → 2H₂O, which maintains both mass and charge balance.
What is the theoretical yield of ethanol?
This question cannot be answered as written. The chemical equation is needed, as well as the masses of the reactants.
Is a chemical equation balanced when each sum of molecules is the same?
No, a chemical equation is balanced when the number of each type of atom is the same on both sides of the equation. This means that the total mass and charge is conserved in a balanced chemical equation.
What represents the correct way to write a chemical equation reactants ----- products products equals reactants reactants equals sum sum ---- reactants?
reactants -----> products is correct
How can the efficiency of a chemical reaction be expressed?
A chemical reaction is represented by a chemical equation.
In a chemical equation the sum of the masses of the products is equal to the sum of the masses of the reactants. True False?
False. In a chemical equation, the total mass of the products is equal to the total mass of the reactants due to the law of conservation of mass. The mass of individual atoms may change during a chemical reaction, but the total mass remains constant.
If you know the molar masses of the reactants in a chemical reaction can you determine the molar masses of the products?
If you know know the molar masses of the reactants in a chemical reaction you can determine the molar masses of the products because the combined molar masses of the reactants equals the combined molar masses of the products.
Can the mole ratio from a balanced chemical equation be interpreted as a ratio of masses?
No, the mole ratio from a balanced chemical equation cannot be directly interpreted as a ratio of masses. The mole ratio represents the ratio of moles of one substance to another in a chemical reaction, whereas the ratio of masses would depend on the molar masses of the substances involved. However, if you know the molar masses of the substances, you can convert between moles and masses using this information.
How does a balanced chemical equation show that mass is never lost or gained in a chemical reaction?
Because the Balanced equation can correctly add the reactants and it will equal the sum of the products.If a chemical equation is balanced correctly, there will be the same number of each element on both sides. Since each element has a given and known mass, the total mass on each side of the balanced equation must be equal.
What law is used to describe a balanced equation?
The law of conservation of mass is used to describe a balanced chemical equation, which states that matter cannot be created or destroyed in a chemical reaction.
When the equation is correctly balanced the sum of the total charge of the reactants is?
When the equation is correctly balanced, the sum of the total charge of the reactants is equal to the sum of the total charge of the products. This ensures that the law of conservation of charge is upheld in the chemical reaction.

Is a chemical equation balanced when each sum of molecules is the same?
No, a chemical equation is balanced when the number of each type of atom is the same on both sides of the equation. This means that the total mass and charge is conserved in a balanced chemical equation.
How much is the total mass of an atom?
The atomic mass is the sum of the masses of protons and neutrons. Electrons have almost no mass and are usually not figured into the equation.
What law is the mathematical relationship between the sum of the masses of the reactants and the sum of the masses of the products?
