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
=====================
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 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.
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 in 2.16 x 10^24 atoms of lead, you would divide the number of atoms by Avogadro's number, which is 6.022 x 10^23 atoms/mol. Thus, 2.16 x 10^24 atoms of lead is equal to 3.59 moles.
There are 1.204 x 1023 atoms in .200 mol of 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.
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 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).
6.747 moles of lead (6.022 X 10^23/1 mole Pb) = 4.063 X 10^24 atoms of lead
0.44 mole Pb (6.022 X 10^23/1 mole Pb) = 2.6 X 10^23 atoms of lead
how many moles are represented by 1.51 x 10^24 atoms 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
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 number of atoms of lead is 6,68.10e23.
That is equal to 0.65 (mol Pb) * 207.2 (g/mol Pb) = 135 grams Pb 207.2 = molar mass of Pb, lead.
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.
