What is the pressure of 5.0 mol nitrogen gas in a 2.0 L container at 286 K
1 answer:
The "Ideal Gas Law Equations" is
P= Pressure (in Pascals)
V=Volume (in Liters)
n=amount, or <u>n</u>umber (in moles)
R= 8.3145
or 
T= Temperature (In Kelvin)
Plug into the equation and you're good!
If your teacher cares about sig figs,
2 sig figs (significant figures)
For other units of pressure,
1 atm = 760 mmHG = 760 Torr = 101326 Pa = 1.01325 bar<u />

<u>Answer:</u> The amount remained after 151 seconds are 0.041 moles
<u>Explanation:</u>
All the radioactive reactions follows first order kinetics.
Rate law expression for first order kinetics is given by the equation:
where,
k = rate constant =
t = time taken for decay process = 151 sec
= initial amount of the reactant = 0.085 moles
[A] = amount left after decay process = ?
Putting values in above equation, we get:
Hence, the amount remained after 151 seconds are 0.041 moles
