To determine the number of atoms in 0.230 g of lead (Pb), you first need to calculate the number of moles of Pb using its molar mass (207.2 g/mol). This can be done by dividing the given mass (0.230 g) by the molar mass of Pb. Next, you use Avogadro's number (6.022 x 10^23 atoms/mol) to convert the moles of Pb to atoms. Therefore, in 0.230 g of Pb, there are approximately 6.58 x 10^21 atoms.

How many moles of Pb are equivalent to 9.51 times 103 g Pb?
To find the number of moles, you need to divide the given mass (9.51 x 10^3 g) by the molar mass of Pb. The molar mass of lead (Pb) is approximately 207.2 g/mol. So, 9.51 x 10^3 g Pb is equivalent to about 45.9 moles of Pb.
How many atoms are in 45 grams of pb?
First of all we convert the mass of leadto moles. Using the equation moles = mass(g) / Ar (Realtive atomic Mass)_. Mass( g) = 45 g Ar =~ 207 (Periodic Table). Hence moles(Pb) = 45 x 207 Moles (Pb) = 9315 moles. Next using the Avogadro number. 1 moles(of A SUBSTANCE) contains 6.022 x 10^(23) atoms. Hence number of atoms in 9315 moles = 9315 x 6.022 x 10^(23) = 5.61 x 10^(27) atoms. As a 'silly' number. 5,610,000,000,000,000,000,000,000,000 atoms.
How many atoms are in 6.755 mole Pb?
there are 6.022 x 1023 atoms in 1 mole, so if you have 6.755 moles of Pb that would be be 6.755(6.022 x 1023) which is 4.067861 x 1024 atoms

What is the number of atoms in 103.6 grams of Pb?
Ready for a bit of dimensional analysis? What we know: 1 mole Pb=207.2g Pb The math part: 103.6gPb x (1molPh/207.2gPb) = 0.500molPb Notice I had 0.500, with two zeros. This is due to significant figures.
How many grams of Pb are formed when 0.105 g NH react?
None. When NH reacts there is no Pb involved and so there is none formed.
What is the mass of 6.25x1020 atoms of lead?
The molar mass of lead (Pb) is 207.2 g/mol. To find the mass of 6.25x10^20 atoms, you need to divide the number of atoms by Avogadro's number (6.022x10^23) to get the number of moles, then multiply by the molar mass of lead. The mass of 6.25x10^20 atoms of lead is approximately 1.72 grams.
