of heat must be added up to the second reservoir to make both reservoirs have the same increase in entropy.
Entropy is the measure of systems thermal energy per unit temperature.
Mathematically,
Entropy = 
ΔS = 
For reservoir first ,
Q (heat) = 400 J
Temperature = 
° C = ° + 273 K
= 243K
Therefore ,
ΔS = 
J/K
For second reservoir,
Q = ?
Temperature = 0° C + 273°
= 273 K
ΔS = 
According to question, Entropy of both the systems are same
Therefore,
= J/K
Q = 
J
Q = 449.38 J

Answer:
Molarity of potassium chloride is 0.100M
Explanation:
Molarity is defined as moles of solute per liter of solvent.
Moles of solute (Potassium chloride; MW: 74.55g/mol):
0.182g × (1mol / 74.55g) = <em>2.44x10⁻³mol KCl</em>
<em />
Liters of water using density are:
26.0g Water × ( 1mL / 1.071g) × (1L / 1000mL) = <em>0.0243L</em>
<em />
Thus, molarity of KCl in the sample is:
<em>2.44x10⁻³mol KCl / 0.0243L = </em><em>0.100M</em>
<em />
I hope it helps!
