Answer:
I think C12 will diffuse faster as it is less dense than C02.
Explanation:
I hope this helps you.
At a fixed temperature and pressure, a cylinder contains equal volumes of O2 and an unknown gas. The identity of the unknown gas CO.
The number of moles of a given substance is calculated by dividing the mass by the molar mass.
The number of moles of O₂ = 
= 0.625 moles.
Based on the given assumption, at fixed temperature and pressure;
- Let assume that the number of moles of the unknown gas is = 0.625 moles
The molar mass of the unknown gas can be estimated as:


= 28 g/mol
Therefore, we can conclude that the unknown gas is CO.

<h3>Answer:</h3>
1.0 × 10⁻⁶ M (Option-A)
<h3>Solution:</h3>
Data Given:
pH = 6
[H⁺] = ?
Formula Used:
As we know pH is given as,
pH = -log [H⁺]
and,
[H⁺] = 10^-pH ----- (1)
Putting value of pH in eq. 1,
[H⁺] = 10⁻⁶ ∴ 10 = Antilog
[H⁺] = 1.0 × 10⁻⁶ M
