Determin the number of oxygen atmos in 1.75kg of potassium sulfate.

Well, let's do some oxygen math, shall we?

The molecular formula for potassium sulfate is K2SO4. Now, let's break it down:

In one molecule of potassium sulfate, we have:

- 2 atoms of potassium (K)
- 1 atom of sulfur (S)
- 4 atoms of oxygen (O)

Now for the fun part: converting grams to moles!

The molar mass of potassium sulfate (K2SO4) is approximately 174.2592 g/mol. So, to determine the number of moles in 1.75 kg, we need to divide the mass by the molar mass.

1.75 kg = 1750 grams

1750 grams / 174.2592 g/mol = approximately 10.049 moles

Since there are 4 oxygen atoms in one molecule of potassium sulfate, the number of oxygen atoms in 1.75 kg would be:

4 atoms/mol * 10.049 moles = approximately 40.196 oxygen atoms

Therefore, in 1.75 kg of potassium sulfate, you would have approximately 40.196 oxygen atoms floating around in the atmosphere! Just kidding, they are all nicely bonded in the compound.

To determine the number of oxygen atoms in 1.75 kg of potassium sulfate, we need to use the molar mass and the chemical formula of potassium sulfate (K2SO4).

The molar mass of potassium sulfate (K2SO4) can be calculated by adding the atomic masses of its constituent elements:

- Potassium (K) has a molar mass of 39.10 g/mol
- Sulfur (S) has a molar mass of 32.07 g/mol
- Oxygen (O) has a molar mass of 16.00 g/mol

The atomic ratio in potassium sulfate is 2:1:4 for potassium, sulfur, and oxygen, respectively.

1. Calculate the molar mass of potassium sulfate (K2SO4):
Molar mass of K2SO4 = (2 × molar mass of K) + molar mass of S + (4 × molar mass of O)
= (2 × 39.10 g/mol) + 32.07 g/mol + (4 × 16.00 g/mol)
= 174.26 g/mol

2. Convert the given mass of potassium sulfate to moles:
Moles of K2SO4 = Mass (in grams) / Molar mass
= 1750 g / 174.26 g/mol
= 10.05 mol

3. Determine the number of oxygen atoms:
Since there are 4 oxygen atoms in one molecule of potassium sulfate (K2SO4), we can multiply the number of moles by the Avogadro's number (6.022 × 10^23 mol^-1) and then multiply it by 4 to find the number of oxygen atoms.
Number of oxygen atoms = Moles of K2SO4 × Avogadro's number × 4
= 10.05 mol × 6.022 × 10^23 mol^-1 × 4
=~ 2.418 × 10^25 oxygen atoms

Therefore, in 1.75 kg of potassium sulfate, there are approximately 2.418 × 10^25 oxygen atoms.

To determine the number of oxygen atoms in 1.75 kilograms (kg) of potassium sulfate (K2SO4), we need to follow a few steps.

Step 1: Calculate the molar mass of potassium sulfate (K2SO4).
Potassium sulfate consists of two potassium atoms (K), one sulfur atom (S), and four oxygen atoms (O). The molar masses of these elements are:
- Potassium (K): 39.10 grams per mole (g/mol)
- Sulfur (S): 32.06 g/mol
- Oxygen (O): 16.00 g/mol

To calculate the molar mass of potassium sulfate, we add up the molar masses of its constituent atoms:
Molar Mass(K2SO4) = (2 * Molar Mass(K)) + Molar Mass(S) + (4 * Molar Mass(O))
= (2 * 39.10 g/mol) + 32.06 g/mol + (4 * 16.00 g/mol)
= 78.20 g/mol + 32.06 g/mol + 64.00 g/mol
= 174.26 g/mol

Step 2: Convert the mass of potassium sulfate given (1.75 kg) to moles.
Since molar mass is given in grams per mole (g/mol), we need to convert the mass from kilograms (kg) to grams (g) first.
1 kg = 1000 g

Mass of potassium sulfate in grams = 1.75 kg * 1000 g/kg
= 1750 g

Number of moles of potassium sulfate = Mass of potassium sulfate in grams / Molar mass of potassium sulfate
= 1750 g / 174.26 g/mol
≈ 10.04 mol

Step 3: Determine the number of oxygen atoms.
From the chemical formula of potassium sulfate (K2SO4), we know that for each unit of K2SO4, there are four oxygen (O) atoms.
So, the total number of oxygen atoms is given by:
Number of oxygen atoms = Number of moles of potassium sulfate * Number of oxygen atoms per mole of potassium sulfate
= 10.04 mol * 4
≈ 40.16 atoms

Therefore, there are approximately 40.16 oxygen atoms in 1.75 kg of potassium sulfate.

1,750 g K2SO4 is how many moles.

1,750 g/molar mass K2SO4.
Then molecules of K2SO4 will number 6.022 x 10^23 molecules in 1 mole. Then there are 4 oxygen atoms per mole K2SO4.
