The formula of trichloromethane is CHCl3. The usual molar formulas of the three elements are C, H2, and Cl2. Based on these formulas, one mole of trichloromethane contains one mole of carbon, one-half mole of hydrogen, and one and one-half moles of chlorine.
CHCl3 is a molecular crystal(when at sold state) so each molecule is in its own individual state (as oppose to ionic compounds or covalent compounds such as SiO2) so in each mole of CHCl3, there would be 1 mol each of carbon atom, hydrogen atom, and 3 moles of chlorine atom
The name trichloromethane shows that each molecule contains three chlorine atoms. Therefore, the answer is 3 X Avogadro's number or about 1.8066 X 1024.

The formula given shows that each formula unit or mole contains one calcium atom; therefore, 2.5 moles of calcium chloride contains 2.5 moles of calcium atoms.
The formula given shows that each formula unit of KCl contains one atom of potassium. Therefore, the number of moles of potassium will be the same as the number of moles of KCl, and its gram formula mass is 74.55. therefore, the number of moles is 125/74.55 or 1.68, to the justified number of significant digits.
The formula unit for calcium is a single atom. Therefore, the number of moles may be found by dividing the given number of atoms by Avogadro's number, or 1.999 moles.
The atomic mass of hydrogen is 1.008 and that for chlorine is 35.45. The moles of hydrogen available are therefore 0.490/1.008 = 0.486 and the moles of chlorine available, 50/35.45, are greater than 1. Each molecule of hydrogen chloride requires one atom each of chlorine and hydrogen. Therefore, with the specified conditions, hydrogen is stoichiometrically limiting, and 0.486 moles of HCl can be made.
molar mass of CHCl3 is119.5gmol-1. so there are 0.49 moles.

The number of moles is 18.56.
0,17 moles of stronium is equal to 1,02376394569.10e23 atoms.
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.
The formula given shows that each formula unit or mole contains one calcium atom; therefore, 2.5 moles of calcium chloride contains 2.5 moles of calcium atoms.
The answer is 1/12,044.10e23.
0,688 g calcium is equivalent to 0,017 moles.

The same number of moles for each.
Absolutely none, as there is no oxygen in hydrogen cyanide. Its formula is HCN--one atom each of hydrogen, carbon and nitrogen.
