WebSequential two-photon ionization is a process that is experimentally accessible due to the use of new free-electron laser sources for excitation. For the prototypical rare Ar gas atoms, a photoelectron spectrum (PES) corresponding to the second step of the sequential two-photon double ionization (2PDIII) at a photon excitation energy of 65.3 eV was studied … WebJun 18, 2024 · Solution. Multiply moles of Ca by the conversion factor (molar mass of calcium) 40.08 g Ca/ 1 mol Ca, which then allows the cancelation of moles, leaving grams of Ca. 10.78 m o l C a ( 40.08 g C a 1 m o l C a) = 432.1 g C a. The total number of atoms in a substance can also be determined by using the relationship between grams, moles, and …
