How many moles of oxygen atoms are present in one half mole of carbon dioxide molecules?
Since each mole of carbon dioxide molecules contains two moles of oxygen atoms, as indicated by the formula CO2 for carbon dioxide, half a mole of carbon dioxide will have one mole of oxygen atoms.
How many H2O molecules are in a mole of water molecules?
A mole of water (H2O) molecules contains approximately 6.022 x 10^23 molecules. This number is known as Avogadro's number. Each mole of water molecules contains this specific number of molecules due to the atomic/molecular weight and mole concept.
How many carbon atoms are there in 200 molecules of C3H8O?
200 molecules C3H8O (1 mole C3H8O/6.022 X 10^23)(3 mole C/1 mole C3H8O)(6.022 X 10^23/1 mole C) = 600 molecules of carbon atoms -------------------------------------------- Of course, you can just look at this set up and see there are 600 molecules. My answer set up is a formal set up. ( 200 * 3 would do it )
Does a mole of helium gas have the same number of molecules as a mole of lead and why?
A mole of anything has the same number of molecules as a mole of anything else. The why comes from the fact that this is the standard definition as agreed by scientists. We have to have standards for things to work. A mole of anything contains an Avagadro number of particles. That number is 6.022 x 1023
How many atoms are in 1 mole of carbon dioxide molecules?
Just one. A molecule is the smallest unit of a substance, so by just having "CO2" implies "1CO2". A coefficient is needed to indicate more than one molecule, such as "6CO2" which is six molecules of carbon dioxide.
How many moles of water are present in half mole of water?
Your question is irrelevant. I think that you were trying to find the number of molecules present in half a mole of water. 1 mole of water contains 6.023 * 1023 number of molecules. Hence half mole contains half of that number of molecules which is 3.0115*1023.
Which quantity is the same for one mole of ethanol and one mole of ethane?
The total number of molecules is equal.
How many carbon atoms are in a molecule of calcium carbonate CaCO3?
A mole of H2 molecules contains 6.023 x 10^(23) H2 molecules or 2 moles of H atoms (since each molecules has 2 atoms). A mole of CaCO3 (calcium carbonate) has one mole (Avogadro number) of Ca atoms, one mole of C atoms and 3 moles of O atoms.
What is the difference between a molecule and a mole of carbon dioxide?
A molecule of carbon dioxide refers to a single unit of CO2 composed of one carbon atom and two oxygen atoms bonded together. A mole of carbon dioxide is a quantity that contains Avogadro's number of molecules (6.022 x 10^23), which is approximately 44 grams of CO2.
What is Avogadro's number the number of?
The number of elementary entities in a mole of the substance. The elementary entities depends on the particles making up the substance. For example, argon is made of single atoms, so a mole of argon simply contains Avogadro's number of atoms. Water, on the other hand, is made of molecules, so a mole of water contains Avogadro's number of molecules. Now each water molecule, H2O, contains 3 atoms so a mole of water contains 3xAvogadro's number of atoms. Sodium chloride, NaCl, is made of sodium and chloride ions, in a ratio of 1:1. So a mole of sodium chloride contains Avogadro's number of sodium ions, and Avogadro's number of chloride ions. A mole of sodium chloride therefore contains 2xAvogadro's number of ions in total. The number comes from the number of carbon atoms in 12g of carbon-12.
What is carbon -12?
one mole of carbon-12 contains 6.02 x 1023 grams of carbon-12
How many carbon atoms are present in a mole of 12C?
A mole of any element contains Avogadro's number of atoms, which is approximately 6.022 x 10^23. Therefore, a mole of ^12C contains 6.022 x 10^23 carbon atoms.
