An unknown gas contains 5.4 moles in 34 mL. If the amount of gas increases to 6.2 moles, what is the new volume?
Murljashka [212]

At constant temperature and pressure, If the amount of gas increases to the given value, its volume also increases to 39 mL.

<h3>What is Avogadro's law?</h3>

Avogadro's law states that "equal volumes of all gases, at the same temperature and pressure, have the same number of molecules."

It is expressed as;

V₁/n₁ = V₂/n₂

Given the data in the question;

  • Initial amount of gas n₁ = 5.4moles
  • Initial volume v₁ = 34mL = 0.034L
  • Final amount of gas n₁ = 6.2moles
  • Final volume v₂ = ?

We substitute our values into the expression above.

V₁/n₁ = V₂/n₂

V₁n₂ = V₂n₁

V₂ = V₁n₂ / n₁

V₂ = (0.034L × 6.2moles) / 5.4moles

V₂ = 0.2108molL / 5.4mol

V₂ = 0.039L

V₂ = 39 mL

Therefore, at constant temperature and pressure, If the amount of gas increases to the given value, its volume also increases to 39 mL.

What precipitate, if any, forms when aqueous solutions of li2so4 and nai are mixed?
aleksandrvk [35]
Hello!

When aqueous solutions of Li₂SO₄ and NaI are mixed the following reaction occurs:

Li₂SO₄(aq) + 2NaI(aq) → 2LiI(aq) + Na₂SO₄(aq)

The compounds produced from this reaction are all soluble, so no precipitate is formed. We know that those compounds (LiI and Na₂SO₄) are soluble because of the solubility rules which states that salts from Group I elements (Li⁺, Na⁺) are soluble.

Have a nice day!
