Some nitrogen for use in synthesizing ammonia is heated slowly, maintaining the external pressure close to the internal pressure
1 answer:
Answer: The work done for the given process is -2188.7 J
Explanation:
To calculate the amount of work done for an isothermal process is given by the equation:
W = amount of work done = ?
P = pressure = 50.0 atm
= initial volume = 542 L
= final volume = 974 L
Putting values in above equation, we get:
To convert this into joules, we use the conversion factor:
So,
The negative sign indicates the system is doing work.
Hence, the work done for the given process is -2188.7 J

Answer:
Conversion factor;
Molar mass;
Avogadro's constant and molar mass
Explanation:
- Firstly, an intermediate step is to define the conversion factor that will be then used in a conversion technique called dimensional analysis in order to convert from one unit to another. An example of a conversion factor would be, for example, 1 L = 1000 mL, which can be manipulated as a fraction, either
or
;
- Secondly, in order to convert mass to moles, we need to know the molar mass of a compound which has a units of g/mol (that is, it shows how many grams we have per 1 mole of substance.
- Thirdly, Avogadro's constant,
tells us that there is
number of molecules or atoms in 1 mole of substance. We need two conversion factors to convert the number of molecules to a mass: firstly, we need to convert the number of molecules into the number of moles using Avogadro's constant and then we need to use the molar mass to convert the moles obtained into mass.
