Answer : The final temperature will be
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 ice =
= specific heat of water =
= mass of ice = 15.0 g
= mass of water = 150 g
= final temperature = ?
= initial temperature of ice =
= initial temperature of water =
Now put all the given values in the above formula, we get
Therefore, the final temperature will be

Molarity is used to measure the concentration of a solution , so it is also as molar concentration. It is denoted as M or Mol/L
<u>We </u><u>are </u><u>given </u><u>that </u><u>:</u>
- Weight of = 5.34g
- Volume of solution = 214 ml , or 0.214 L
The molar mass of magnesium chloride ( ) is 95.21 g / mol
We can calculate the molarity of the solution by dividing the number of moles of solute by volume of solvent in liter ,i.e:
ㅤㅤㅤ⸻( 1 )
<em>Where,</em><em> </em>
- M = molarity
- n = number of moles
- V = Volume
We can calculate the number of moles by dividing the actual mass by its molar mass ,i.e:
ㅤㅤㅤ⸻ ( 2 )
<em>W</em><em>here,</em>
- n = number of moles
- m = molar mass
- w = actual mass
