1 mol Pb = 207.2 grams
12.4 mol Pb = ? grams (cross multiplication)
mass of (12.4 mol Pb) = (207.2 gr *12.4 mol) / (1mol)
= 2569.28 g
To find the number of moles of Pb in 2.3456g, you first need to determine the molar mass of Pb, which is 207.2 g/mol. Next, you can use the formula: moles = mass / molar mass. Substituting the values, moles = 2.3456g / 207.2 g/mol = 0.0113 moles of Pb.
To find the number of moles of atoms in 1.00 lb of lead, you would first convert the weight to grams (1 lb = 453.592 grams), then divide by the molar mass of lead (207.2 g/mol). This calculation would give you the number of moles of lead atoms in 1 lb of lead, which is approximately 2.19 moles.
To determine the number of moles of lead in 1.50 x 10^12 atoms, you can use Avogadro's number, which is 6.022 x 10^23 atoms/mol. First, calculate the number of moles by dividing the number of atoms given by Avogadro's number. ( \frac{1.5 \times 10^{12}}{6.022 \times 10^{23}} = 2.49 \times 10^{-12} ) moles 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.
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.
If 17,4 is grams the number of moles is 0,084.
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.
To find the grams of lead in 4.62 moles, you can use the molar mass of lead, which is approximately 207.2 g/mol. Multiply the number of moles by the molar mass to get the grams: 4.62 moles * 207.2 g/mol ≈ 956.6 grams of lead.
To find the number of moles of Pb in 2.3456g, you first need to determine the molar mass of Pb, which is 207.2 g/mol. Next, you can use the formula: moles = mass / molar mass. Substituting the values, moles = 2.3456g / 207.2 g/mol = 0.0113 moles of Pb.
To find the number of moles of atoms in 1.00 lb of lead, you would first convert the weight to grams (1 lb = 453.592 grams), then divide by the molar mass of lead (207.2 g/mol). This calculation would give you the number of moles of lead atoms in 1 lb of lead, which is approximately 2.19 moles.
To calculate the mass of 1.2044 × 10²⁴ atoms of lead (Pb), first determine the number of moles using Avogadro's number (approximately 6.022 × 10²³ atoms/mol). The number of moles is calculated as ( \frac{1.2044 \times 10^{24}}{6.022 \times 10^{23}} \approx 2.00 ) moles. The molar mass of lead is about 207.2 g/mol, so the mass is ( 2.00 , \text{moles} \times 207.2 , \text{g/mol} \approx 414.4 , \text{grams} ).
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.
To find the number of atoms in 10 grams of lead, you would first need to determine the number of moles of lead (using the molar mass of lead) and then use Avogadro's number (6.022 x 10^23 atoms/mol) to calculate the number of atoms. This would be approximately 1.15 x 10^23 atoms in 10 grams of lead.
Using the formula number of moles = mass divided by molar massso mass = number of moles X molar massFind molar mass by adding up the masses of all the atoms in your substance.A good way to remember this is as the formula g/mw = moles, and the mnemonic for this is"Mine workers (mw= molecular weight) under ground (grams of compound you are dealingwith = Moles!
5 moles of lead is equal to 1 036 g.
Atomic mass: 207.2 grams.455 moles × (6.02 × 1023) = 2.74 × 1023 atoms of lead
To determine the number of moles of lead in 1.50 x 10^12 atoms, you can use Avogadro's number, which is 6.022 x 10^23 atoms/mol.
