Answer: 2.186 m
Explanation:
formula for molality: (mol solute)/(kg solvent)
Na2CO3 = solute
510g Na2CO3 * ( 1 mol / 106 g) = 4.811 mol solute
ethylene glycol = solvent
2.2 * 10^3 g * ( 1 kg / 1000 g) = 2.2 kg
(4.811/2.2) = 2.186
Given what we know, the tool in question that will help the student collect data regarding the transfer of kinetic energy between water and ice would be a thermometer.
<h3>How does the thermometer measure kinetic energy?</h3>
It does not do so directly. However, kinetic energy in water molecules is reflected in the temperature of the water. When water molecules increase their kinetic energy and move more, they become hotter. Increased or decreased heat is an indirect way to measure the transfer of kinetic energy in water.
Therefore, given that the temperature of the water is a reflection of the transfer of kinetic energy happening, we can confirm that the tool that will help the student collect the data needed is a thermometer.
