You first have to find how many moles of CO2 you have

so you find its molar mass, (Carbon=12 Oxygen = 16(2))

then you add 12+32 to get the molar mass which is 44

you should also be given a mass, of how much CO2 there is..

or else you cannot calculate the moles.

moles are mass/molar mass

once you get the moles

just multiply the number of moles by

Avogadros constant (6.02x1023)

Say if the mass was 4.56 g of C02 that you had

then you just do 4.56/44 = 0.103636363 mol

now multiply that by avogadro's constant

and you have the number of atoms/particles/formula units

To determine the number of atoms in CO2, you look at the chemical formula. In this case, CO2 means one carbon atom (C) and two oxygen atoms (O) making a total of three atoms in a molecule of carbon dioxide.

How many atoms is 110 grams of CO2?

To find the number of atoms in 110 grams of CO2, you first need to determine the number of moles by dividing the mass by the molar mass of CO2 (44.01 g/mol). Next, you can use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms. So, there are approximately 2.5 x 10^24 atoms in 110 grams of CO2.


How many atoms of O are needed to combined with 0.00000000003 atoms of carbon to form CO2?

For every molecule of CO2, you need 1 atom of carbon and 2 atoms of oxygen. So to combine with 0.00000000003 atoms of carbon, you would need 0.00000000006 atoms of oxygen, which cannot be physically represented as a fraction of an atom.


How many atoms are in each CO2 molecule?

three: one carbon and two oxygen


What are the number of carbon atoms and oxygen atoms in 2 molecules of carbon dioxide?

One molecule of CO2 has one carbon atom and two oxygen toms. denoted by the formula CO2 So in two molecules of CO2 there are CO2 & another CO2 . Chemically this is shown as 2CO2, that is a figure is placed to the left of the molecular formula. Since there are CO2 & another CO2 , then there are two(2) atoms of carbon and four(4) atoms of oxygen.

How many atoms of each kind of element are there in in a molecule of carbon dioxide?

One Carbon (C) atom and two Oxygen atoms (O). CO2.


In two molecules of carbon dioxide 2CO2 there are how many atoms and what are they made of?

2 CO2 means there are two molecules of carbon dioxide. In one molecule of CO2 there is 1 carbon atom, and 2 oxygen atoms. So three atoms total. Therefore, in 2 molecules (each with 3 atoms) there are 6 atoms total. The molecules are made of atoms of carbon and oxygen. The atoms themselves are made of protons, electrons, and neutrons.


How many atoms total are in one moleclue?

The number of atoms in a molecule depends on its formula. The definition of a mole is approximately 6.022 x 10^23 entities (like atoms or molecules). For example, a molecule of water (H2O) contains 3 atoms - 2 hydrogen and 1 oxygen.


How many oxygen atoms are in the produced what reaction c6h12o6 plus 6 h2o plus 6 co2 plus 12h2o?

your equation is wrong.  it should be  c6h12o6 + 6 o2 --> 6 co2 + 6h2o The products contain 18 oxygen atoms  (so do the reactants)


How many atoms per element does carbon dioxide have?

Carbon dioxide (CO2) contains three atoms per molecule: one carbon atom and two oxygen atoms.
