The number of grams of sulfur in 223 grams of sodium sulfate is . . . Grams And explain how, I still dont get it fully

Answers

Answer 1

Answer:

50.25 g of sulphur, S.

Explanation:

Mass of Na₂SO₄ = 223 g

Mass of sulphur =?

Next we shall determine the molar mass of Na₂SO₄. This can be obtained as follow:

Molar mass of Na₂SO₄ = (23×2) + 32 + (16×4)

= 46 + 32 +64

= 142 g/mol

Mass of S in 142 g of Na₂SO₄ = 32 g

Finally, we shall determine the mass of S in 223 g of Na₂SO₄. This can be obtained as follow:

142 g of Na₂SO₄ contains 32 g of S.

Therefore, 223 g of Na₂SO₄ will contain = (223 × 32) / 142 = 50.25 g of S.

Thus, 223 g of sodium sulfate, Na₂SO₄ contains 50.25 g of sulphur, S.

Will there ever be grams of a limiting reactant remaining after a reaction has stopped? Why or why not?

Answers

Assuming the reaction is complete, there should be no limiting reactant remaining after a reaction. This is because the limiting reactant, by definition, is "the reactant that is completely used up in a reaction."

Which mass is made up of 6.02x10^23 atoms? none of these 23 g sodium 42 g krypton 24 g carbon 78 g potassium

Answers

Answer:

23 g sodium

Explanation:

In chemistry, one mol (1mol) of a substance equals Avagadro's number or constant (6.02 × 10^23 atoms/particles/molecules).

According to this question in which the mass of different elements were given, the mass of the element that equals 6.02 × 10^23

Using the formula; mole = mass/molar mass

- Sodium = 23g/23g/mol = 1mol

- Krypton = 42g/84g/mol = 0.5mol

- Carbon = 24g/12g/mol = 2mol

- Pottasium = 78g/39g/mol = 2mol

Therefore, from the above illustration, it can be observed that only 23g of sodium contains 1 mol, hence, 23g sodium contains 6.02 × 10^23 atoms.

What is the mass of 3.25 moles of sodium hydroxide (NaOH)?

Answers

Answer:

1 mole is equal to 1 moles NaOH, or 39.99711 grams.

Explanation:

Hope this helps have a nice day :)

The statement of the mass of sodium hydroxide (NaOH) is "130 g."

What is mass?

A substance is something to do with mass that takes up space. The mass of a compound is the total amount of atoms present in grams that make up a molecule. The grams is the unit of mass.

In order to determine the mass in grams, multiply moles of the substance value by its molar mass to convert moles into grams.

Mole to gram conversion factor,

[tex]=\;given \;mole\;.\;\frac{grams}{1\;mol}[/tex]

Mass of NaOH comes out to be,

[tex]=\;3.25\;mol\;.\;\frac{39.997\;g}{1\;mol}[/tex]

= 129.99 g

= 130 g

Hence the correct answer is 130 g.
