Question

A college student wants to toss a textbook to his roommate who is leaning out of
a window directly above him. He throws the book upwards with an initial velocity
of 8.0 m/s. The roommate catches it while it is traveling at 3.0 m/s (up). a)
How long was the book in the air? b) How far vertically did the book travel? A
car accelerates in a straight line from rest at the rate of 2.3 m/s 2. What is its
final velocity after 55 m? What is its time?​

Answer 1

Answer:

A solution of acetic acid (CH3COOH), methanol (CH3OH), and water is prepared such that the mole fraction of acetic acid is 0.01335, and the mole fraction of methanol is 0.03288. The density of the solution is measured to be 0.9889 g/mL. What is the molarity (in M) of acetic acid in this solutionA solution of acetic acid (CH3COOH), methanol (CH3OH), and water is prepared such that the mole fraction of acetic acid is 0.01335, and the mole fraction of methanol is 0.03288.
