P1 x V1 P2 x V2
______ = ________
T1 T2
1260 x 23 / 200 = 144.9
1595x V/300
144.9= 1595x V/300
144.9 x 300/1595 = v

Answer:
Explanation:
Answer:
A. to determine the efficiency of the reaction
Explanation:
Percentage is the ratio of the actual yield to theoretical yield as a percentage. It is calculated by dividing the actual yield by theoretical yield then multiplying by 100%.
Calculation of percentage yield is important as it helps in the determination of efficiency of a reaction. For example in most industries for the purpose of making the most product with the least waste.
Additionally, calculating the percentage yield helps in determining other products that may be formed during the reactions.
Respuesta:
3 L
Explicación:
Paso 1: Información provista
- Volumen inicial del gas (V₁): 4 L
- Presión inicial del gas (P₁): 0,79 atm
- Volumen final del gas (V₂): ?
- Presión final del gas (P₂): 1,05 atm
Paso 2: Calcular el volumen final del gas
Si suponemos que el gas se comporta como un gas ideal y que la temperatura permanece constante, podemos calcular el volumen final del gas usando la ley de Boyle.
P₁ × V₁ = P₂ × V₂
V₂ = P₁ × V₁ / P₂
V₂ = 0,79 atm × 4 L / 1,05 atm = 3 L
