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

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.
