you have 0.375 mol of palladium atoms how many atoms are present
2 Answers

in 1 mol of any substance which is pure there is 6.022 x 10^23 atoms (Avogadros number)
so in 0.375 mol of pure Palladium there is (0.375 x 6.011 x 10^23) atoms
= approx. 2.26 x 10^23 atoms

?atoms=0.375 mol * (6.022*10^23 atoms/ 1 mol)
so mol will be simplified with mol, and the number of atoms will remain.
0.375*6.022*10^23 atoms
