I am taking Chemistry and I am work on some practice problems. I have no idea how to do this one and the book does not explain it well. So could any one help me and show me how to do it!

    1 cm = 10 mm , 1mm = 0.1 cm

    1 min = 60 sec, 1 sec = 0.016 min

    350 mm/sec = 350 * (0.1/0.016) cm/min

    350 mm/sec = 2187.5 cm/min

    1.2 ppm = (1.2/10^6)*100 = 0.00012 %

    Well this is just simple maths unless I'm very wrong..How is that a Chemistry question lol?

    You just divide 350 by 100 (because that would convert mm to cm) then u divide again by 60 (to convert seconds to mins, 60 seconds in a min blah blah)

    So I make the answer to be 0.0583(with the 3 recurring I cant do the dot lol)
