How many times an atom of calcium is heavier than an atom of oxygen?
Average atomic mass of Ca = 40.1 Average atomic mass of O = 16.0 Mr(Ca)/Mr(O) = 40.1/16.0 = 2.51 Thus the calcium atom is about 2.5 times heavier than the oxygen atom.
Why does the stratosphere have less oxygen than the troposphere?
We know that oxygen is just a bit heavier than the air like carbon dioxide ,nitrogen etc.Besides that the main source of oxygen,the trees is in troposphere. Because of this reasons oxygen density is much heavier in troposphere than the stratosphere

Is oxygen heavier than hydrogen?
Hydrogen is lighter than Oxygen. This is a very simple question. Hydrogen is the first element on the periodic table of elements and it weighs 0.08988 grams per litre. Oxygen is the 8th element on the periodic table. It weighs 1.429 grams per litre. All of the elements (and most chemicals you will ever want to know about) have an article on Wikipedia. These articles almost always include the "weight per amount" known as Density.
Why does a bike get heavier after rusting?
A bike gets heavier after rusting because rust is the result of iron reacting with oxygen in the air to form iron oxide. Iron oxide has a greater mass than iron alone, adding to the weight of the bike.
Are there any gasses heavier than lead?
polymorphos
Why is water heavier than the two gasses that compose it?
fluids are heavier than gases. When hydrogen its by itself is lighter than water as so the oxygen is also lighter. Once combined they form a fluid thus the combination of two gases produced a fluid which will turn heavier.
Is nitrogen heavier than oxygen?
it is heavier
What is heavier oxygen or CO2?
CO2 carbon dioxide is heavier than oxygen.
What gas is heavier hydrogen or oxygen?
oxygen gas is heavier than hydrogen gas
Is carbon dioxide lighter than oxygen?
The molecular weight of carbon dioxide is heavier than oxygen. Oxygen has a molecular weight of 32 g/mol, while carbon dioxide has a molecular weight of 44 g/mol. Therefore, carbon dioxide is heavier than oxygen.
Which element is heavier than carbon but lighter than oxygen?
If "heavier than" in the question is interpreted to mean "has an atomic mass greater than", the answer is nitrogen
What gas is heavier ammonia or oxygen?
Oxygen (1,429 g/cm3) is more dense than ammonia (o,70 g/cm3).
Which is more heavier - hydrogen gas or oxygen gas?
Mass of Hydrogen gas:- 2g/mol Mass of Oxygen gas :- 32g/mol Therefore, Oxygen gas is more heavier
What kind of air is heavier than another type of air?
Gas is heavier than oxygen. Cold air is heavir than hot air
How is oxygen gas heavier?
Oxygen gas is considered heavier than other gases (like nitrogen and helium) because the oxygen molecule (O2) has a higher molecular weight due to its two oxygen atoms bonded together. This higher molecular weight causes oxygen gas to be denser and therefore heavier than some other gases.
How many times heavier is one atom of carbon than one atom of oxygen?
It isn't. Carbon is 6th on the Periodic Table and Oxygen is 8. Oxygen is the heavier element. mass of oxygen / mass of carbon 15.99g / 12.01g = 1.33 heavier than carbon
