How many atoms are in 45 grams of pb?
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.
What is the mass of 6.25x1020 atoms 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.
How many atoms of calcium are in 1.00 g?
There are 6.02 x 10^23 atoms of calcium in 1 gram of calcium.
How many atoms are in 141 g of calcium?
The molar mass of calcium is 40.08 g/mol. To find the number of atoms in 141 g of calcium, divide the given mass by the molar mass and then multiply by Avogadro's number (6.022 x 10^23). This will give you approximately 2.12 x 10^23 atoms in 141 g of calcium.
How many atoms of copper equal a mass of 127.10 g?
To find the number of atoms of copper in 127.10 g, you first need to calculate the number of moles using the molar mass of copper (63.55 g/mol). Then, use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms. In this case, 127.10 g of copper is equivalent to approximately 1.00 x 10^23 atoms.
How many atoms are in 0.230 g 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.
How many atoms are in g Pb?
The number of atoms of lead is 6,68.10e23.

Which one has a greater mass..2 atoms of lead or 0.000000000000000000000051 mole of helium?
207.2/ 6.022*10^23 = 34.4 x 10-23 g, mass of 1 Pb atom For two atoms: 34.4*2= 68.8 x 10-23 g Pb 5.1*10^-23*4.003 g He (atomic mass) / 1 mol He= 20.4*10^-23 g He And the mass of lead is greater.
How many molecules is in 291.25g of Pb's?
291.25 grams of lead (1 mole Pb/207.2 grams)(6.022 X 10^23/1 mole Pb) = 8.4648 X 10^23 atoms of lead I think you meant to say atoms, not molecules, as that is not a molecular formula and looks a lot like the symbol for lead with a possessive mark and s.
How many atoms are in 6.755 mole 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
how many atoms are in 22 g of argon?
The answer is 3.32*10^23 atoms
What is the mass of 6.25x1020 atoms 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.
How many atoms do six grams of diamond have?
Diamond is made of up carbon. So, it has a molar mass of 12 g/mol. 6 g/mol / 12 g = 0.5 mol 0.5 mol * 6x10^23 atoms/mol = 3x10^23 atoms There are 3x10^23 atoms in six grams of diamond.
How many moles are represented by 32.50 g Mg?
how many moles are represented by 1.51 x 10^24 atoms Pb
What is the number of atoms in 103.6 grams 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.
How many moles of Pb are equivalent to 9.51 times 103 g 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.
