A water (H2O) molecule consists of two hydrogen atoms and one oxygen atom. The oxygen atom is located at the origin. One hydrogen atom is between the positive x-axis and positive y-axis and the other hydrogen atom is between the negative x-axis and the positive y-axis. Each hydrogen atom makes an angle of 60º with the positive y-axis and they are both a distance d = 0.0957 Å from the origin. Draw a rough sketch of the water molecule and then calculate the center of mass of the water molecule. The mass of oxygen is 16.0 g and of hydrogen is 1.0 g.
