A Hi-Vol Sampler Draws Air At An Average Rate Of 70 Ft3/min.
A hi-vol sampler draws air at an average rate of 70 ft3/min. If the measured particle concentration is 200 ~g/m3 and the hi-vol was operated for 12 hours, what was the weight of dust on the filter?
Answers
It depends on the particle size(s) and the grade of the filter.

You have posted a series of quite complex scientific / engineering problems and haven't really asked for "help", actually solutions. If you really are starting to tackle them a couple of hours before they are due, then that's bad planning. You really need to have a chat with your tutor and get some help.
Somebody needs to be looking after your interests since you don't appear to be doing so. Doing your assignments for you won't help in the long run. You need parental type advice to realise you need to take in lectures, course, and book studies in good time, or else you'll gain no real understanding or capability. Go see your tutor and 'turn over a new leaf' regarding your college strategy, or you'll gain little by being there.
