At STP, what physical property of aluminum always remains the same from sample to sample?

1 answer:

4 0

At STP, the physical property of aluminum that always remains the same from sample to sample is density. The standard temperature is actually 273 degree kelvin and the standard pressure is 1 atmospheric pressure. I hope that this is the answer that has actually come to your desired help.

Answer:

126.73 mL

Explanation:

The total pressure of the gas mixture is the sum of the vapor pressure of its constituents. So, the vapor pressure of N₂O(p) can be calculated:

750 = 18.85 + p

p = 750 - 18.85

p = 731.15 torr

It means that for 731.15 torr, N₂O occupied 130 mL. For the general gas equation, we know that

$\frac{p1V1}{T1} = \frac{p2V2}{T2}$

Where p is the pressure, V is the volume, T is the temperature, 1 is the initial state, and 2 the final state. For the same temperatue (21ºC), the equation results on Boyle's law:

p1V1 = p2V2, so:

731.15x130 = 750xV2

750V2 = 95049.5

V2 = 126.73 mL
