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
A formula unit of the nitrate salt of Q is Q(NO3)2.
<h3>What is IUPAC nomenclature?</h3>
The IUPAC nomenclature was put together by the international Union of Pure and applied chemistry in order to have a uniform way of naming compounds.
We shall now find the names of the compounds;
1) Na* and HPO4²- ; sodium hydrogen tetraoxophoshate V
2) Potassium cation and cyanide anion ; Potassium cyanide
3) Calcium cation and hypochlorite anion; Calcium oxochlorate I
Knowing that the valency of NO3^- is one and that the compound formed between Q and CO3²- has the formula QCO3 we can conclude that a formula unit of its nitrate salt is Q(NO3)2.
