<>"On addition to water the Na+ section of NaCl is attracted to the oxygen side of the water molecules, while the Cl- side is attracted to the hydrogens' side of the water molecule. This causes the sodium chloride to split in water, and the NaCl dissolves into separate Na+ and Cl- atoms."<>
Answer:

Explanation:
Hello,
In this case, based on the given, we can infer that as titanium is hot and water cold, it cools down whereas the water is heated up, therefore, in terms of heat, we have that the heat lost by the titanium is gained by the water:

That in terms of mass, specific heat and temperatures is:

In such a way, for computing the mass of titanium, considering the heat capacity of water 4.18 J/g°C, we have:
