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
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.
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.
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).
