9.51 X 103 grams Pb (1 mole Pb/207.2 grams)
= 45.9 moles of lead
===============
(9.51)*(103 ) grams Pb (1 mole Pb/207.2 grams )
= 4.73 moles of lead
3.0 X 1024 atoms of Pb (1 mole Pb/6.022 X 1023)
= 5.0 moles lead
===========
9,3.10 ex.15 lead atoms is equal to 1,544.10 ex.-18 moles.
7.95x105 grams Pb is equivalent to 3 836,9 moles.

45.9 mol Pb
The balanced equation for the reaction is 2 C4H10 + 13 O2 -> 8 CO2 + 10 H2O. This shows that 13 moles of diatomic oxygen are required to burn 2 moles of butane. By proportionality, (4.8/2)13 or 31.2 moles of oxygen are required to burn 4.8 moles of butane. This corresponds to 31.2(32) or 1.0 X 103 grams of oxygen.
One mole=1000 Milli moles One mole=6.022 x 1023 molecules of the substance Therefore, one Milli mole of ammonia has 6.022 x 1023 /103 = 6.022 x 1020 molecules of ammonia.
