can you help w/ 1b? **Problem 1: Salt in Boiling Water for Pasta**When making pasta, people often add salt to the boiling water before adding the pasta. Assume that two teaspoons of salt (12 grams) is added for every one quart of water (0.95 liters = 1 quart), and that sodium chloride completely dissociates. Also assume that the density of tap water is 1.0 g/ml and the density of the salt water solution is 1.015 g/ml. The tasks are:**a. What is the molality of the salt water solution?****b. What is the molarity of the salt water solution?****c. Calculate the boiling point of the salt water solution.**

(1b) Given that - Mass of salt NaCl = 12 g Volume of water = 1 quart = 0.95 L = 950 mL Density…

Why are ducks waterproof? It’s because they produce copious amounts of oils from their uropygial glands and spread it across their feathers. In this exercise, we’ll be investigating the molecular structure of one of these preen oils to determine how it keeps ducks dry. Q.5 - Preen oil is actually a complicated mixture of many different organic compounds, such as the structure seen previously.. Ornithologists have determined that birds often use preen oil compounds for scent recognition. Below, several different chemicals isolated from preen oil are shown, along with their vapor pressures at room temperature. p-cymene has the highest vapor pressure, meaning it is the most easily evaporated compound of the three listed. Explain why p-cymene has a higher vapor pressure at room temperature compared to the other compounds. Make sure to explain what holds the p-cymene in the sample. (Image attached)
