1.2 l sample of gas is determined to contain 0.5 moles of nitrogen. at the same temperature and pressure, how many moles of gas would there be in a 20 l sample?

A 20 L sample of the gas contains 8.3 mol N₂.

According to Avogadro’s Law, if p and T are constant

V₂/V₁ = n₂/n₁

n₂ = n₁ × V₂/V₁

n₁ = 0.5 mol; V₁ = 1.2 L

n₂ = ?;           V₂ = 20 L

∴n₂ = 0.5 mol × (20 L/1.2 L) = 8.3 mol

b. acid is the correct answer @jayxboof all social media

acid : acids are those which accepts an electron-pairs.

base : bases are those which donates ab electron-pairs.

alkali : it is a base that dissolves in water. it is basically a base and the ph greater than 7.

hydroxide ion : it is a poly-atomic ion which is negatively charged.

ill try to . no promises tho.
