Pb molecular weight is 207.2 g/mol. 33.3 moles of Pb weighs 6899.76 grams.
33.12 grams lead (1 mole Pb/207.2 grams)(6.022 X 1023/1 mole Pb)
= 9.626 X 1022 atoms of lead
=====================
5 moles of lead is equal to 1 036 g.
If 17,4 is grams the number of moles is 0,084.
1,4 moles of lead(II) oxide are formed.
Mole times Lead's Molecular mass(Mr) gives you its mass And I think the Mr of Lead is 207
16 grams of oxygen how many moles is 0,5 moles.
2.3456 grams lead (1 mole Pb/207.2 grams) = 0.01132 moles of lead =================
5 moles of lead is equal to 1 036 g.
If 17,4 is grams the number of moles is 0,084.
Atomic mass: 207.2 grams.455 moles × (6.02 × 1023) = 2.74 × 1023 atoms of lead
1,4 moles of lead(II) oxide are formed.
A lot! 9.51 X 103 grams Pb (1 mole Pb/207.2 grams) = 45.9 moles of lead ===============
Mole times Lead's Molecular mass(Mr) gives you its mass And I think the Mr of Lead is 207
you calculate the number of moles by working out the gram formula mass of Lead II iodide, which should be 461.03 g/mol, and divide that by the measured ammound of substance you have in grams. That will give you the number of moles of substance you have.
For this you need the atomic mass of Pb. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel..0015 moles Pb × (207.2 grams) = .311 grams Pb
16 grams of oxygen how many moles is 0,5 moles.
2.8 moles of gold would be 550g of gold. Multiplying the amount of moles by the molar mass (197.0 grams/moles) will give you the grams by cancelling out the moles units.
