How many atoms are in 0.230 g Pb?
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 atoms are in .23 g Pb?
To find the number of atoms in 0.23 g of lead (Pb), you first need to determine the number of moles using the molar mass of lead. Lead has a molar mass of approximately 207.2 g/mol. Then use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms.
How many moles are represented by 32.50 g Mg?
how many moles are represented by 1.51 x 10^24 atoms Pb
How many atoms are in 0.200 mol of pb?
There are 1.204 x 1023 atoms in .200 mol of Pb.
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

How many atoms are in point 44 mole of Pb?
0.44 mole Pb (6.022 X 10^23/1 mole Pb) = 2.6 X 10^23 atoms of lead
How many molecules is in 291.25g of Pb's?
291.25 grams of lead (1 mole Pb/207.2 grams)(6.022 X 10^23/1 mole Pb) = 8.4648 X 10^23 atoms of lead I think you meant to say atoms, not molecules, as that is not a molecular formula and looks a lot like the symbol for lead with a possessive mark and s.
