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.
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.
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.
6.755 moles lead (6.022 X 1023/1 mole Pb) =6.755 x 6.022 X 1023 =4.068 X 1024 atoms of lead =====================
To find the number of lead atoms in 4.001018 reams of lead, you first need to convert the number of reams to moles using the molar mass of lead. Then, use Avogadro's number (6.022 x 10^23) to convert moles of lead to lead atoms.
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
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).
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.
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.
8.90 X 1023 lead atoms (1 mole Pb/6.022 X 1023)(207.2 grams/1 mole Pb) = 306 grams of lead =============
There are 1.204 x 1023 atoms in .200 mol of Pb.
The number of atoms of lead is 6,68.10e23.
To find the mass of 1.00 x 10^12 lead atoms, you would first determine the molar mass of lead (Pb), which is 207.2 g/mol. Then, divide the total number of atoms by Avogadro's number to get the number of moles, and finally multiply by the molar mass to get the mass. So, the mass of 1.00 x 10^12 lead atoms is approximately 3.14 x 10^-9 grams.
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.
To calculate the number of atoms in 80 grams of lead, you first need to determine the number of moles of lead using its molar mass (207.2 g/mol). Then, you can use Avogadro's number (6.022 x 10^23) to convert moles to atoms. So, for lead, there are approximately 3.86 x 10^23 atoms in 80 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 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.
Let us do this in two parts for clarity. Find atoms in tin first. 10 grams tin (1 mole Sn/118.7 grams)(6.022 X 1023/1 mole Sn) = 5.07 X 1022 atoms of tin ----------------------------------- 5.07 X 1022 atoms (1 mole Pb/6.022 X 1023)(207.2 grams/1 mole Pb) = 17 grams of lead ------------------------------ I can see two other ways to do the conversion string, one longer and one much shorter. See if you can find them.
