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.
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
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 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, 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.
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.
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
The moles are converted into a number of particles by multiplying 6.02 by 10(with the power of 23)
To find the number of atoms in 45 grams of Pb (lead), we need to first calculate the number of moles. The molar mass of Pb is approximately 207.2 g/mol. By dividing the given mass by the molar mass, we can find the number of moles. Then, we can convert moles to atoms using Avogadro's number (6.022 x 10^23 atoms/mol).
