How many oxygen atoms are there in the formula 2CO2?
There are 4 oxygen atoms in the formula 2CO2. Each CO2 molecule contains 2 oxygen atoms, so when you have 2 CO2 molecules, you get a total of 4 oxygen atoms.
What is the number of elemnts is CO2?
There are two elements in CO2, carbon and oxygen.
What does the 2 in CO2 means?

How mony moles of oxygen atoms do 1.5 moles of Co2 contain?
0.75 moles of any substance is 0.75(6.02x1023) = 4.52x1023 particles. If those particles are CO2 molecules, and each molecule has 2 oxygen atoms, then it's 2(4.52x1023) = 9.04x1023 oxygen atoms.
How many total atoms are in CO2?
6 - the 2 in front means 2 molecules of CO2 and the 2 after the O means 2 oxygen atoms per molecule of CO2, so 2 molecules composed of 3 atoms = 6 atoms

What does the subscription indicate in the chemical formula co2?
The 2 indicates that there are 2 oxygen atoms.
What are the number of carbon atoms and oxygen atoms in 2 molecules of carbon dioxide?
Carbon dioxide: CO2. The number to the right of the symbol for an element indicates how many atoms of that element are present in single molecule. If there is no number then there is one atom present. Then in the case of carbon dioxide there must be one atom of carbon (C) and two atoms of oxygen (O). Double these to provide the numbers of atoms of the two elements in two molecules: two of carbon, four of oxygen.
How many oxygen atoms are in 52.06g of carbon dioxide?
In 52.06g of carbon dioxide (CO2), you have 1 mole of CO2, which contains 2 moles of oxygen atoms. Each mole of oxygen atoms is equivalent to 6.022 x 10^23 atoms. Therefore, in 52.06g of CO2, there are 2 x 6.022 x 10^23 oxygen atoms.
What does the subscript 2 mean in the chemical formula CO2?
it means there are 2 molecules of O (oxygen) in the compound CO2
What does CO2 contain?
A chemistry related answer: It contains elements Carbon and Oxygen, and together they make Carbon Dioxide (CO2). One carbon, and two oxygen molecules..
Does Co2 contain 2 elements and 3 atoms?
yes, because it contains carbon and oxygen, with 2 oxygen atoms and 1 carbon atom.
Determine the number of oxygen atoms present in 25.0g carbon dioxide?
Carbon Dioxide-CO2 To get molecules, we must convert grams to moles and moles to atoms using Avogadro's number. Molar mass of CO2= C:12.0g+O:16.0gx2=44.0g CO2 25.0g CO2 | 1 mol CO2 | 6.02x10 23 molecules CO2 ------------------------------------------------------------------- = 3.42x10 23 molecules CO2 1 | 44.0g CO2 | 1 mol CO2 Now to get the number of oxygen atoms. Since there are 3 atoms in CO2 and 2 of them are oxygen, we will divide by 3 (1.14x10 23) and multiply by 2 (2.28 x10 23) So the number of oxygen atoms in 25.0 grams of CO2 is 2.28x10 23 or 228 000 000 000 000 000 000 000
