Answer : The final equilibrium temperature of the water and iron is, 537.12 K
Explanation :
In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.
where,
= specific heat of iron = 560 J/(kg.K)
= specific heat of water = 4186 J/(kg.K)
= mass of iron = 825 g
= mass of water = 40 g
= final temperature of water and iron = ?
= initial temperature of iron =
= initial temperature of water =
Now put all the given values in the above formula, we get:
Therefore, the final equilibrium temperature of the water and iron is, 537.12 K
The empirical formula for the given compound has been . Thus, option C is correct.
The empirical formula has been the whole unit ratio of the elements in the formula unit.
<h3>Computation for the Empirical formula</h3>The given mass of Sulfur has been, 50.05 g
