One pound is 0.4536 kg. 44g is the molar mass of CO2, so:
44 g contain the Avogadro number of carbon atoms, 6.023 x 10^23
so 1 g contains 6.023/44 x 10^23 atoms
1 kg contains 6.023/44 x 10^26 atoms
0.4536 kg contain 6.023 x 0.4536/44 x 10^26 atoms
= 6.209 x 10^24 atoms.
One pound! (Though it's difficult to get it to stay on the scale!!)
one ton (2,000 pounds)
Three atoms. Carbon dioxide is CO2
one
Carbon dioxide: CO2 Atoms of oxygen (16O, 17O, 18O) and atoms of carbon (12C, 13C, 14C).
three: one carbon and two oxygen
One carbon and 2 oxygens = 3
Three atoms. Carbon dioxide is CO2
The chemical formula of carbon dioxide is CO2; the molecule contain one carbon atom and two oxygen atoms.
one
1 mole of CO2 has 1 mole of carbon atoms and 2 moles of oxygen atoms. So, 0.000831 mole of CO2 will have 0.000831 mole of carbon atoms.
The formula is CO2, so there is one atom of carbon and two atoms of oxygen in each molecule.So there are 2.5x10^21 atoms of carbon in that many molecules of CO2.
Carbon dioxide: CO2 Atoms of oxygen (16O, 17O, 18O) and atoms of carbon (12C, 13C, 14C).
1 mole of CO2 has 1 mole of carbon atoms and 2 moles of oxygen atoms.
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.
no. of atoms = no. of moles * avogadros no. no. of atoms = 6 * 6*1023 no. of atoms = 3.6*1024 (ans)
One Carbon (C) atom and two Oxygen atoms (O). CO2.
Carbon Dioxide, or CO2, has one Carbon molecule and two Oxygen molecules.
CO2 (carbon dioxide) has 1 carbon atom and 2 oxygen atoms.
