At constant temperature and pressure, If the amount of gas increases to the given value, its volume also increases to 20.85L.
<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 = 2moles
- Initial volume v₁ = 13.9L
- Final amount of gas n₁ = 3moles
V₁/n₁ = V₂/n₂
V₁n₂ = V₂n₁
V₂ = V₁n₂ / n₁
V₂ = (13.9L × 3moles) / 2moles
V₂ = 41.7molL / 2mol
V₂ = 20.85L
Therefore, at constant temperature and pressure, If the amount of gas increases to the given value, its volume also increases to 20.85L.

Answer:
To convert C to K, just add 273, remember that 0° C is 273 K, so 73.a) is 317.2 K and 73.c) is 253 K. 74.a) Will be, -129, 4 C + 273 = 143.5 F, 74.c) 663.8 F
75.a) 7.2 C , 75.c) -23.3 C
Explanation:
To convert C to F, you can use this, (9/5 * C + 32 ) = F, or back ward, C = (F - 32)* 5/9.

Explanation:
Hello,
In this case, considering that the heat due to a change in temperature is given by:
Whereas Q accounts for the heat, m for the mass, Cp for the heat capacity and ΔT the change in the temperature, therefore, the mass turns out:
Best regards.
