Question:
On a hot (95 F) summer day the relative humidity reaches an uncomfortable 85%. At this condition, the water vapor mole fraction is 0.056. Treating the moist air as an ideal-gas mixture of water vapor and dry air, determine the mass fraction of water vapor and the apparent molecular weight of the moist air. Treat the dry air as a simple substance with a molecular weight of 28.97 kg/kmol.

I have experience teaching math, science, and English to students of all ages. I have also worked as a tutor in a college setting, helping students with their homework and preparing them for exams.
I believe that tutoring is a great way to help students learn. It allows students to get one-on-one help with their studies, and it gives them the chance to ask questions and get immediate feedback. Tutoring can also be tailored to the individual needs of the student, which is why I believe it is so effective.
I have seen firsthand how tutoring can help students improve their grades and confidence. I have also seen how it can help students who are struggling with a particular subject. I believe that tutoring is a great way to help students learn and succeed in school.
