To solve the problem, we need to calculate the observed rotation when a solution of (R)-2-butanol is mixed with a racemic mixture of 2-butanol. Here are the steps to arrive at the solution: ### Step-by-Step Solution: 1. **Identify the Given Information:** - Concentration of (R)-2-butanol = 0.1 M - Concentration of racemic 2-butanol = 0.05 M - Volume of each solution mixed = equal volumes ...
