20 4. A sample containing ethanol and water was found to have n = 1.3400. Calculate the exact percentage of ethanol and water in this example. Show your work. (Hint: Solve this mathematically. Assume a linear relationship between concentration and refractive index. You can make the y-intercept the refractive index of water, and use the slope formula to find the slope. The x axis (concentration) will be from 0% ethanol to 100% ethanol. From this information, you can get the equation of the line, then plug in your numbers from there.)
