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.
2 x O3 = 6 of O so 6 x 6.023 x 1023 = 3.6138 x 1024
6. 1 mole of CS2 contains 1 mole of carbon and 2 of sulfur.
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
To calculate the number of moles of carbon atoms in dichlorobenzene, we need to determine the molar mass of C6H4Cl2. The molar mass is 147.009 g/mol. Using the given mass of 3.982 g, we can calculate the number of moles using the formula moles = mass/molar mass. So, moles of C6H4Cl2 = 3.982 g / 147.009 g/mol = 0.0271 moles of C6H4Cl2. Since there are 6 carbon atoms in each molecule of C6H4Cl2, the number of moles of carbon atoms would be 6 times the moles of the compound, which is 0.0271 moles x 6 = 0.1626 moles of carbon atoms.
Assuming each Tums tablet contains 500 mg of calcium carbonate, there is a total of 6 grams of calcium carbonate in one roll of Tums (12 tablets x 500 mg). To calculate the number of moles, divide the mass by the molar mass of calcium carbonate (100.09 g/mol), yielding around 0.06 moles of calcium carbonate in one roll of Tums.
In 1.5 moles of CaCl2, you would have 3 moles of ions or atoms of calcium and 3 moles of ions of chloride. Since CaCl2 dissociates into 1 calcium ion (Ca2+) and 2 chloride ions (2Cl-), this means you would have 3 moles of calcium ions and 6 moles of chloride ions in total.

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
There are 9.33 moles of carbon in 5.62 atoms of carbon.
2 moles of benzene gives 12 moles of hydrogen atoms since benzene is C6H6
2 x O3 = 6 of O so 6 x 6.023 x 1023 = 3.6138 x 1024
In Ca(HCO3)2, there are 2 moles of carbonate ions (CO3^2-), each containing 3 atoms. So there are 6 atoms in 1 molecule of Ca(HCO3)2. Therefore, in 4 moles of Ca(HCO3)2, there are 4 x 6 = 24 moles of atoms.
The molecular weight of Calcium Bromide is extremely close to 200. So 1200/200 = 6 moles present.
4,37.10e-18 C atoms are equivalent to 7,25.10e-6 moles.
Each molecule of C6H6 contains 6 carbon atoms, so when 1 mole of C6H6 decomposes, 6 moles of carbon atoms are obtained. Therefore, in a 1.68 mole sample of C6H6, 6 × 1.68 = 10.08 moles of carbon atoms can be obtained from the decomposition.
There are a total of 13 atoms in 3CaCl2: 3 calcium atoms and 6 chlorine atoms.
There are a total of 10 atoms in 3CaCl2. This includes 3 calcium atoms (Ca) and 6 chlorine atoms (Cl).
