How many moles of a gas will 700 m hold at -100 oC and 86 atm?
1 answer:
0.23 moles of a gas will 700 m hold at -100 oC and 86 atm.
Explanation:
given that:
volume = 700 ml OR 0.7 Litre (for converting into litre it is divided with 1000 as 1 litre = 1000ml)
temperature = -100 degrees OR 173.15 K
pressure = 86 atm
R = 0.082057 L atm mol-1K-1
n=?
It is known that when Volume is taken in litres, pressure in atm, and temperature in Kelvin then R= 0.082057 L atm mol-1K-1,
From the formula for ideal gas:
PV = nRT
putting the values in the formula:
n =
=
= 0.23 moles of the gas will be required.

Explanation:
Hello there!
In this case, according to the given information it will be firstly necessary to set up the chemical equation taking place:
We infer we need to calculate the moles of NH3 by using both of the moles of N2 and H2 at the beginning, in order to identify the limiting reactant:
Thus, since hydrogen yields the fewest moles of ammonia, we conclude that we are just able to yield 4 moles of NH3.
