Answer : The final temperature of the mixture is
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 =
= specific heat of water =
= mass of iron = 39.9 g
= mass of water =
= final temperature of mixture = ?
= initial temperature of iron =
= initial temperature of water =
Now put all the given values in the above formula, we get
Therefore, the final temperature of the mixture is
Answer:
The molarity of the solution is 0.29
Explanation:
Molarity, or molar concentration, is a measure of the concentration of a solute in a solution, be it some molecular, ionic or atomic species. It is defined as the number of moles of solute that are dissolved in a given volume.
Molarity is calculated as the quotient between the number of moles of solutes and the volume of the solution:
Molarity is expressed in units .
In this case:
- number of moles of solute= 2.1 moles
- volume= 7.3 liters
Replacing:
Molarity= 0.29
<u><em>The molarity of the solution is 0.29 </em></u><u><em></em></u>
