=================
0.44 mole Pb (6.022 X 10^23/1 mole Pb) = 2.6 X 10^23 atoms of lead
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.
To find the number of moles, we can use Avogadro's number. There are 6.022 x 10^23 atoms in 1 mole of any element. Therefore, for 3.4 x 10^24 Pb atoms, the number of moles would be 3.4 x 10^24 atoms / 6.022 x 10^23 atoms/mol.
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.
3Pb(NO3)2 + 2AlCl3 = 3PbCl2 + 2Al(NO3)3 Is the balanced equation.If there are 8 moles of ALCl3 used instead of 2, the number of moles need of the first reactant needed will be 6 moles.The new balanced equation is: 6Pb(NO3)2 + 8AlCl3 = 6PbCl2 + 8Al(NO3)3
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.
89 grams of Pb(CH3COO)4 is equal to 0,2 moles.
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
how many moles are represented by 1.51 x 10^24 atoms Pb
The molar mass of lead (Pb) is approximately 207.2 g/mol. To find the mass of 33.3 moles of lead, you would multiply the number of moles by the molar mass: 33.3 moles * 207.2 g/mol = approximately 6890.76 grams of lead.
That is equal to 0.65 (mol Pb) * 207.2 (g/mol Pb) = 135 grams Pb 207.2 = molar mass of Pb, lead.

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.
To find the number of moles, we can use Avogadro's number. There are 6.022 x 10^23 atoms in 1 mole of any element. Therefore, for 3.4 x 10^24 Pb atoms, the number of moles would be 3.4 x 10^24 atoms / 6.022 x 10^23 atoms/mol.
The balanced chemical equation for the reaction between plumbous nitrate and cupric sulfate is: Pb(NO3)2 + CuSO4 → PbSO4 + Cu(NO3)2 From the equation, we can see that 1 mole of plumbous nitrate (Pb(NO3)2) reacts with 1 mole of cupric sulfate (CuSO4). Therefore, 0.25 moles of cupric sulfate will require 0.25 moles of plumbous nitrate for complete reaction.
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.
