Anastasy [175]

Answer:

P=10 atm

Explanation:

Hola,

En este caso, usando la ecuación del gas ideal, podemos calcular facilmente la presión a partir de:

PV=nRT

Por lo que despejando para la presión obtenemos:

P=\frac{nRT}{V}

Así, calculamos:

P=\frac{10mol*0.082\frac{atm*L}{mol*K}*(27+273)K}{24.6L} \\\\P=10 atm

¡Saludos!
