We know that , 1 mole of substance contain Avogadro's number of particles.
1 mole of P4O10 will contain 6.022 10 23 P4O10 molecules.
P4O10 molecules present in 4.31 mol P4O10 = 4.31 mol P4O10 (6.022 10 23 P4O10 molecules /1 mol P4O10
P4O10 molecules present in 4.31 mol P4O10 = 2.595 10 24 P4O10 molecules
ANSWER : 2.60 10 24 P4O10 molecules
PART 2
mol of P4O10 present in 1.07 10 22 P4O10 molecules
= 1.07 10 22 P4O10 molecules ( 1 mol P4O10 / 6.022 10 23 P4O10 molecules )
= 1.7768 10 -03 mol P4O10
ANSWER : 1.78 10 -03 mol P4O10
