I mention the number of questions in a sentence like "I have following 3 questions:" and then write them down as a numbered list. I think this makes it more obvious if an answer is missing. However, if an answer is missing, I just ask that question again (maybe rephrased), without pointing out that a question was missed - "It is not clear to me yet [...]" It works at least sometimes.
