Answer:
1.02KPa
Explanation:
The following were obtained from the question:
V1 = 1550mL
P1 = 70.26kPa
T1 = 480°C = 480 + 273 = 753K
T2 = -237°C = - 237 + 273 = 36K
V2 = 5114mL
P2 =?
The final pressure can obtain as follows:
P1V1/T1 = P2V2/T2
(70.26x1550)/753 = (P2x5114)/36
Cross multiply to express in linear form as shown below:
P2 x 5114 x 753 = 70.26 x 1550 x 36
Divide both side by 5114 x 753
P2 = (70.26x1550x36)/(5114x753)
P2 = 1.02KPa
Therefore, the final pressure is 1.02KPa
You could ask whether the black crust is a new substance formed from silver underwent a chemical change because a chemical change produces a new substance.
