1 mole of carbon (or 12 g) has 6 x 1023 atoms.
So, 3 moles of carbon (or 36 g) has 18 x 1023 atoms
What else can I help you with?
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 )
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.
How many atoms are in 9.7x10-3 mole C?
There are approximately 5.8x10^21 atoms in 9.7x10^-3 moles of carbon. This is calculated by multiplying Avogadro's number (6.022x10^23 atoms/mol) by the number of moles of carbon.
How many carbon atoms are present in three moles of 12C?
One mole of 12C contains Avogadro's number of carbon atoms which is approximately 6.022 x 10^23. Therefore, three moles of 12C would contain 3 times Avogadro's number of carbon atoms, which is approximately 1.807 x 10^24 atoms.
How many moles of carbon atoms are there in 3 grams of carbon?
The questions asks how many moles of carbon atoms.Molar mass is defined as the mass of one mole of a substance or in this case 6.022x1023 atoms of carbon. So the molar mass for carbon is 12.0 g/mol. Therefore the number of moles of carbon atoms is just 36/12.0 = 3.0 moles of carbon.How many atoms are in 36 grams of Carbon?[36 (gC) /12.0 (gC/molC)] * 6.02*10+23 (atoms C/molC) = 1.8*10+24 atoms in 36 g Carbon
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 carbon are in 3.5 moles of calcium carbonate?
The number of moles of calcium carbonate are 3.5 moles. , there are 1 mole of calcium (Ca) atom, 1 mole of carbon (C) atom and 3 moles of oxygen (O) atoms.
How many atoms are ther in 3.5 mol of carbon?
1 mole of any substance contains 6.02x1023 representative particles. That is called Avogadro's number, and it's one of the most important constants in science. So, 3 moles of carbon would be 3 times that, which would be 18.06x1023, which simplifies to 1.806x1024 atoms.
How many atoms are in 6.1x10-3 moles of carbon?
6,1x10-3 moles of carbon 36,7350592277.1020 atoms.
How many moles are in Li2O?
1 mole of Li₂O contains 2 moles of lithium (Li) atoms and 1 mole of oxygen (O) atoms. Therefore, in 1 mole of Li₂O, there are a total of 3 moles of atoms.
How many atoms of hydrogen are in 2NH3?
1 mole NH3 (3 mole H/1 mole NH3) = 3 mole hydrogen atoms
Calculate no of C and O atoms present in 11.2Liters of carbon dioxide at STP?
co2 c = (6.02times 10^23) /2 o = (6.02 times 10^23) /2 To calculate the number of any atoms/molecules at STP you times it by a "Mole" ( 6.022 x 1023) as stated above. So first you get how many molecules there are using the mole, then find out how much Carbon and Oxygen are in CO2 [1Carbon, 2 Oxygen]. Since there are 3 atoms to every molecule of CO2 [as stated in the line above] you divide the number by 3, then take that answer and times it by 1 to get the number of Carbon [3 parts, 3/3 = 1 (one part Carbon)] And likewise to Oxygen [3/3 = 1 (x2) = 2 Oxygen atoms for every one Carbon] Once you have that you times your answer of Carbon by 11.2 [because the answer stated above is only for one Liter]. And times your answer for Oxygen by 11.2 for the same reason.
