<span>C) Density of the particles of solute in the solution</span>
Answer: You will have 10 iron moles
Explanation: This is due to the law of conservation of mass. The amount of atoms going in the reactant side of a reaction has to be equal to the amount of atoms in the product side
The term absolute zero is given because the volume and the temperature comes to 0. So according to Charles law,
<span>At const K temp, </span><span>Volume is proportional to Temperature. </span>So the volume is also 0. <span>P = nRT/V. </span><span>T=0 and P=0</span>
The answer is a, because the question is referring to partial pressures. Partial pressures are a mere sum, no halving or doubling of anything is necessary.
So, A
