Solar flares form when prominences connect I think
Answer:
Resolution is the ability to distinguish two objects from each other. Light microscopy has limits to both its resolution and its magnification.
(NH4)3PO4 :
N = 14 * 3 = 42
H = 1 * 12 = 12
P = 31 * 1 = 31
O = 16 * 4 = 64
-------------------------
42+12+31+64 = 149 g / mol
