N(quartz) = 1.46, not 146.
Snells's law is
N1*sin(theta) = N2*sin(theta2)
In your case, solve for N2.
1.46 sin45 = N2*sin 22
N2 = 1.46*(.70711)/(.37461) = 1.8876

A beam of light passes from the fused quartz of a bottle (n = 1.46) into the ethyl alcohol (n = 1.36) that is contained inside the bottle. If the beam of the light inside the quartz makes an angle of 25.0° with respect to the normal of both substances, at what angle to the normal will the light enter the alcohol?
