Answer:

To calculate the mass of 2 moles of SO2 and 1 x 10^22 S8 molecules, you need to use the terms molar mass and Avogadro's number.

1. Calculate the molar mass of SO2:

- The atomic mass of sulfur (S) is 32 g/mol.

- The atomic mass of oxygen (O) is approximately 16 g/mol.

- SO2 consists of one sulfur atom and two oxygen atoms.

- Therefore the molar mass of SO2 is:

Molar mass of SO2 = (1 x atomic mass of S) + (2 x atomic mass of O)

= (1 x 32 g/mol ) + (2 x 16 g/mol)

= 32 g/mol + 32 g/mol

= 64 g/mol

2. Calculate the mass of 2 moles of SO2:

- Now with the molar mass of SO2, you can calculate the mass of 2 moles of SO2 using the formula:

Mass = mol x molar mass

Mass of 2 moles of SO2 = 2 mol x 64 g / mol

= 128 g

So the mass of 2 mol SO2 is 128 grams.

3. Calculate the mass of 1 x 10^22 S8 molecules:

- First we find the molar mass of S8 (one molecule contains about 8 sulfur atoms).

Molar mass of S8 = (8 x atomic mass of S)

= (8 x 32 g/mol)

= 256 g/mol

- Now, learn more you want 1 x 10^22 Mass of S8 molecule:

Mass = number of molecules x molecules

1 x 10^22 Mass of S8 molecule = (1 x 10^22 molecules) = 2.56 x 10^24 g

So the mass of 1 x 10^22 S8 molecule is 2.56 x 10^24 g.

Summary:

- The weight of 2 mol SO2 is 128 grams.

- The mass of 1 x 10^22 S8 molecule is 2.56 x 10^24 grams.

Step-by-step explanation:

Of course, let's calculate the mass of 2 moles of SO2 (sulfur dioxide) and 1 x 10^22 S8 (sulfur) molecules.

1. Mass of 2 mol SO2:

The molar mass of SO2 is the sum of the atomic masses of the sulfur (S) and oxygen (O) elements in it.

- Atomic mass of S = 32 g/mol

- Atomic mass of O = 16 g/mol

The molecular formula of SO2 is that it has one sulfur atom and two oxygen atoms. indicates what it contains. . atoms:

SO2 = S + 2O

Therefore, the molar mass of SO2 is:

Molar mass of SO2 = (1 * atomic mass of S) + (2 * atomic mass of O mass) Mass of SO2 = (1 * 32 g/mol) + (2 * 16 g/mol)

Molar mass of SO2 = 32 g/mol + 32 g/mol

Molar mass of SO2 = 64 g/mol

Now we want to find the mass of 2 moles of SO2. The relationship between mol (n), molar mass (M) and mass (m) is given by:

m = n * M

For 2 mol SO2:

m = 2 mol * 64 g / mol

m = 128 g

So the weight of 2 mol SO2: 128 grams

2. 1 >

The molecular formula of S8 shows that it has 8 sulfur atoms:

S8 = 8S

> Number of moles of S8 Mass:

Molar mass of S8 = 8 * Atomic mass of S mass

Molar mass of S8 = 8 * 32 g/mol

Molar mass of S8 = 256 g/mol >

Now we want to find the mass of 1 x 10^22 S8 molecules. First, we must calculate the number of moles using Avogadro's number; This number tells us that 1 mole of a substance contains approximately 6,022 x 10^23 molecules.

Number of moles of S8 = (1 x 10^22 molecules) / (6.022 x 10^23 molecules/mol)

Number of moles of S8≈ 1.66 x 10^-2 mol< br>

Now we can calculate the mass:

m = n * M

m = (1.66 x 10^-2 mol) * (256 g / mol)

m ≈ 4.26 gram

Therefore, the mass of 1 x 10^22 S8 molecules is approximately 4.26 grams.
