A mole contains 6.022 x 10^23 atoms, which is also known as Avogadro's number, and this number is same for each element. So, there are 2 x (6.022 x 10^23) = 12.044 x 10^23 atoms in 2 moles of Calcium.

How many atoms and are there in 36g of water?
1 mole of water is 18g. 36g of water is thereforeequivalent to 2 moles. 2 moles of water contains 4 moles of hydrogen and 2 moles of oxygen and so there are6 moles of atoms in 2 moles of water. 6 moles of atoms x (3.6x10^24) = 36.1x10^24 atoms
How many moles of sulfur atoms are present in 3.00 moles of cs2?
6. 1 mole of CS2 contains 1 mole of carbon and 2 of sulfur.
How many oxygen atoms are present in a 14.0 g sample of Cu(NO3)2?
14.0 g x 1 mole/187.56 g = 0.0746 moles0.0746 moles Cu(NO3)2 x 6 moles O/mole Cu(NO3)2 = 0.448 moles O atoms0.448 moles O atoms x 6.02x10^23 atoms/mole = 2.70x10^23 atoms of oxygen
How many nitrogen atoms are in CaNO33?
Ca(NO3)2Number of atoms in the compound:Ca- 1N- 2O- 6Find the atomic masses of all atoms and add:Ca = 40.1N = 2 * 14.0 = 28.0O = 6 * 16.0 = 96.0___________________164.1 gEquation:# moles * added atomic mass = # gramsAnswer:4.2 moles * (164.1 g) = 689.22 grams of Ca(NO3)2
How many atoms in iron oxide Fe2O3?
There are 6 atoms of oxygen represented by this.
How many atoms does Calcium Nitrate have?
6,022 x 1023 atoms/mole. Calcium nitrate = Ca(NO3)2 .There are 1 mole of calcium making 6,022 x 1023 atoms of calcium.There are 2 moles of nitrate-ions and each nitrate-ion is made up of 1 mole nitrogen, and 3 moles of oxygen. Thath means that the nitrate ion in calcium nitrate has 6 moles oxygen and 2 moles of nitrate:Atoms of nitrogen: 6,022 x 1023 moles-1 x 2 moles = 1,2044 x 1024 atomsAtoms of oxygen: 6,022 x 1023 moles-1 x 6 moles = 3,6132 x 1024 atoms
How many moles of carbon are in 5.62 atoms of carbon?
There are 9.33 moles of carbon in 5.62 atoms of carbon.
How many moles are in 1200 grams of calcium bromide?
The molecular weight of Calcium Bromide is extremely close to 200. So 1200/200 = 6 moles present.
How many atoms and are there in 36g of water?
1 mole of water is 18g. 36g of water is thereforeequivalent to 2 moles. 2 moles of water contains 4 moles of hydrogen and 2 moles of oxygen and so there are6 moles of atoms in 2 moles of water. 6 moles of atoms x (3.6x10^24) = 36.1x10^24 atoms
How many moles of carbon are present in 4.37x1018?
4,37.10e-18 C atoms are equivalent to 7,25.10e-6 moles.
How many atoms are there in one mole of ammonium chloride?
Ammonium chloride has the formula of NH4Cl. Thus, in each mole there are 4 moles H, 1 mole N and 1 mole Cl for a total of 6 moles of atoms. Then 6.02x10^23 atoms/mole x 6 moles = 3.6x10^24 atoms.
How many atoms are in 3 CaCl2?
3 CaCl2 has 3 calcium atoms and 6 oxygen atoms.
How many moles of oxygen atoms are contained in one mole of BaNO32?
9 moles (there are four oxygen atoms for every mol of BaSO4, so you multiply 2.25 by 4)
