Many processes such as the fabrication of integrated circuits are carried out in a vacuum chamber to avoid reaction of the material with oxygen in the atmosphere. it is difficult to routinely lower the pressure in a vacuum chamber below 1.0*10^-10 torr. a)calculate the molar density at this pressure at 310. bwhat fraction of the gas phase molecules initially present for 1.0 in the chamber are present at ?

Part A: Your composite function would be plugging in your s(w)=40w in for the s in f(s)=2s+30

Your expression would be

2(40w)+30

80w+30= your given expression

Part B: The units for the composite function in Part A would be:

number of flowers

Part C: You would plug 35 in for the w in our expression in part A

80*35+30

2,800+30

2,830

Hope this helps ;)
