Answer
The index of refraction of the glass is $~~1.48$
Work Step by Step
We can use Snell's law to find $n_2$:
$n_2~sin~\theta_2 = n_1~sin~\theta_1$
$n_2 = \frac{n_1~sin~\theta_1}{sin~\theta_2}$
$n_2 = \frac{1.00~sin~32.0^{\circ}}{sin~21.0^{\circ}}$
$n_2 = 1.48$
The index of refraction of the glass is $~~1.48$.
