However, the surface oxide layer is not very thick, so in practical terms the difference is going to be small (and since the total mass of a current US penny is 2.5 grams and only 2.5% of that is copper, even if every bit of copper were totally oxidized we're talking about a mass difference of well under 1%).

∙ 11y agoYes, since oxygen from the air combines with the copper on the penny's surface, the mass of the oxygen is added to the mass of the original penny.
2 Cu + O2 → 2 CuO
According to the equation above, 1 mole of copper reacts with 1 mole of oxygen to produce 2 moles of copper II oxide.
Mass of 2 moles of Cu = 2 * 63.5 = 127 grams
Mass of 1 mole of O2 = 32 grams
Mass of 2 moles of CuO = 2 * (63.5 + 16) = 159 grams
This means 127 grams of copper reacts with 32 grams of oxygen to produce 159 grams of copper II oxide.

What instrument would be best to determine how different oxidation states affect the mass of a carbon based compound?
Mass spectrometry would be the best instrument to determine how different oxidation states affect the mass of a carbon based compound. Mass spectrometry is capable of accurately measuring the mass-to-charge ratio of ions, allowing for the identification of the compound and its various oxidation states based on their mass differences.
What is the Mass of a 1984 penny?
The mass of a 1984 penny is approximately 2.5 grams.
What is the mass of a penny in kilograms?
The mass of a penny is approximately 2.5 grams, which is equal to 0.0025 kilograms.
Why doesn't the penny get clean with water?
Water doesn't react with the oxidation on the coin.
What causes oxidation on a penny?
Oxidation on a penny is caused by the reaction of the copper in the penny with oxygen in the air. This forms copper oxide, which gives the penny a dull brown color. Moisture and other environmental factors can accelerate the oxidation process.
Why does cold temp affect oxidation?
because of science
What is the corrosion on a penny?
The corrosion on a penny is typically a greenish-blue substance called copper oxide that forms when the copper in the penny reacts with oxygen in the air and moisture. This process is known as oxidation and can give the penny a dull or tarnished appearance.
Do pennies gain mass over time?
Yes, pennies can gain mass over time due to oxidation and corrosion which can cause the surface to accumulate dirt and contaminants. This can make the penny weigh more without actually adding metal.
How many pennies make 500 grams?

What have more inertia a penny or basketball?
The basketball has more inertia because it has more mass than a penny. Inertia is directly related to an object's mass - the larger the mass, the greater the inertia.
What is the mass of an American penny?
about .4 grams
How do Oxidation agents affect the natural and artificial color pigment?
Oxidation agents can affect natural and artificial color pigments by breaking down the color molecules and causing them to change in appearance. In natural pigments, oxidation agents can lead to color fading or browning. In artificial pigments, oxidation agents can cause color loss or changes in hue.
