A 43g titanium rod at 100 °C was placed in a cup filled with 237 ml of water at 23°C and the final temperature was 87 °C. Find the specific heat of titanium. Specific heat of water is (4.18 J/g.C), the density of water is 1.01 g/mL.

I need help with these (Not honor class) (Not grading)

I know you don't answer graded questions and I am not looking for you to straight up give me the answer to this but how do I even start? like I said before I know that the highest peak is 16amu which is Oxygen but do I just the vertical bar as a ratio? Like the next bar to the left (15amu?) is like 90% intensity? so like 9:10 ratio? There isn't even a 15amu element so please just give me some idea where to start. The place in the book it tells you to go to read has nothing about this stuff, its about finding empirical formulas from mass or percentages.... please help me!

3. Consider a solution containing dipolar molecules each having a positively charged head and a negatively charged tail. In the absence of an electric field the molecules point north (n), south (s), east (e), and west (w) with equal probabilities (distribution shown in Fig. 3a). A different probability distribution (shown in Fig. 3b), however, is found when a field is applied to the solution. P P 14 n e น S 7 16 14 16 n e W s Fig. 3a (field absent) Fig. 3b (field present) a) Determine the direction in which the field has its most positive pole (the polarity of the field). b) In the absence of the field, what is the entropy of the system? c) In the presence of the field, what is the entropy of the system? d) Does the application of the field cause the system to become more ordered or disordered?
