The answer is A...
Well one is usually heavier than the other plate so i think A
(P1)(V1)/(T1)=(P2)(V2)/(T2)
Set up as: (P1)(V1)(T2)/(T1)(P2)=(V2)
P1=207torr
V1=30.0L
T1=-268°C
P2=101.3kPa (Same as 760torr)(use torr to make it easier though)
T2=20.0°C
Make sure all °C is in Kelvin
°C + 273 = Kelvin
Numbers are now:
P1=207torr
V1=30.0L
T1=5K
P2=760torr
T2=293K
Set them up as shown above
Should look like this:
(207torr)(30.0L)(293K)/(5K)(760torr)=V2
As long as you do them in that order you should get: 478.82L
You can also round to get 479L
Either one is correct.
Answer: I think it’s B. Because as you can see from the picture there are layers
Explanation:
I think but just in case ask for a second opinion
Answer:
from,
moles,n = <u>number</u><u> </u><u>of</u><u> </u><u>particles</u><u>,</u><u> </u><u>N</u>
Avogadro constant
N = 8.27 * 6.022×10^23
N = 4.98 × 10^ 24particles.
In 8.27 moles of SiH, there are
4.98 × 10^24particles.
