A node has one entering activity, A, and two leaving activities, B and C.
a. Given the following information, determine the latest finishing time for activity A (show work using an activity on node network diagram): EFB = 36, EFC = 33, LFB = 41, LFC = 35; activity times are A = 4, B = 7, C = 4.
b. What is the slack for each activity?
Ever since volume is proportional to the number of moles present mole fractions of gases can be expressed as ratios of volumes at the same temperature and pressure. Compute the concentration of each gas in moles per liter at 0°C.
