QPOE Files
The x-ray data are stored in QPOE files (Quick Position-Ordered Events, *.qp) rather than image arrays. These are lists of photons identified by several quantities, including the position on the detector, pulse height, and arrival time. Note that, unlike IRAF images, QPOE files have no associated header file, and are always stored in the current directory, unless explicitly specified otherwise. Non-PROS IRAF tasks can also access QPOE data files in place of image arrays.

Answer:
12.78
Explanation:
pOH= -log(0.0600) = 1.22184875
pH= 14-1.22184875 = 12.78
Mass number = proton number+ neutron number
m=92+143
=235
