Answer:
Both molarity and formality express concentration as moles of solute per liter of solution. Formality is a substance's total concentration in solution without regard to its specific chemical form. ... The formality of a solution is defined as the number of formula mass of any solute dissolved in 1 litre of solution.
He can conclude that his experiment has very low precision.
<h3>What is Precision ?</h3>
Precision is defined as the degree of refinement with which an operation is performed or a measurement .
Precision is how close the exact answers are together.
As, the answers are increasing in time.
None of the answers are similar to one another.
Hence, He can conclude that his experiment has very low precision.

Answer:
The solidifying/cooling and crystallizing of magma causes igneous rocks to form.
Answer:
an alkali
Explanation:
an alkali is a base that is slightly soluble in water
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.
