Question

A lab technician measures a sample of sulfur dichloride (SCl2) to contain 4.31 x 10^22 molecules of SCl2. How many atoms of chlorine are present in the sample?

Answer 1

THE NUMBER OF ATOMS OF CHLORINE IN THE SAMPLE IS 25.95 * 10^45 ATOMS.

Step-by-step explanation:

Number of molecules = 4.31 * 10^22 molecules of SCl2

From Avogadro's rule which states that equal volume of gases at the same temperature and pressure have the same number of molecules.

1 mole = 6.022 * 10 ^ 23 particles or atoms

So therefore, we equate the given value of SCl2 molecules and solve for the number of atoms of chlorine in the molecule

1 mole = 6.022 * 10^23 atoms

From the break down of SCl2

SCl2 -------> S+ + 2Cl -

So therefore, 2 moles of chlorine is present

2 moles = 2 * 6.022 *10^23

4.31 * 10^22 moles = x atoms

= 4.31 * 10 ^22 * 2 * 6.022 * 10^23 / 2

= 25.95482 * 10^45 atoms

In conclusion, the number of atoms of chlorine present in the sample is 25.95 * 10^45 atoms.
