What has the most atoms one mole of gold helium or lead?
1 mole atoms of all atoms of any element will always have the same number of atoms and will be equal to 6.023 x 1023 atoms. However the weight will vary. 1 mole = 4 g of Helium or 197 g of gold or 207 g of lead
What is the mass of 8.90 x 1023 lead atoms?
8.90 X 1023 lead atoms (1 mole Pb/6.022 X 1023)(207.2 grams/1 mole Pb) = 306 grams of lead =============
What has a greater number of atoms a gram of lead or a gram of uranium?
The lead atom is way heavier than the helium atom. We know this by referring to the Periodic Table of Elements. The atomic mass of lead (Pb) is 207, while that of helium (He) is 4. Therefore, we can estimate that an atom of lead is about 50 times heavier than an atom of helium.
How many atoms are there in 80 grams of lead?
Pb has a MW of 207.2 g/mol. Thus, 80g of Pb is 80/207.2 = 0.39 mol of lead. Using Avogadro's number: (6.0221415 * 1023 atoms/mol)(0.39 mol) = 2.349 * 1023 atoms.
Does a mole of helium gas have the same number of molecules as a mole of lead and why?
No, a mole of helium gas does not have the same number of molecules as a mole of lead. This is because the number of particles in a mole is determined by Avogadro's number, which is approximately 6.022 x 10^23. Since helium is a monoatomic gas and lead is a solid with a lattice structure, the number of helium atoms in a mole is significantly larger than the number of lead atoms in a mole.
What has the most atoms one mole of gold helium or lead?
1 mole atoms of all atoms of any element will always have the same number of atoms and will be equal to 6.023 x 1023 atoms. However the weight will vary. 1 mole = 4 g of Helium or 197 g of gold or 207 g of lead
What is the mass of 8.90 x 1023 lead atoms?
8.90 X 1023 lead atoms (1 mole Pb/6.022 X 1023)(207.2 grams/1 mole Pb) = 306 grams of lead =============
How many atoms are in 0.455 moles of lead?
Atomic mass: 207.2 grams.455 moles × (6.02 × 1023) = 2.74 × 1023 atoms of lead
How many atoms are there in 6.755 mol 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 =====================
What has a greater number of atoms a gram of lead or a gram of uranium?
The lead atom is way heavier than the helium atom. We know this by referring to the Periodic Table of Elements. The atomic mass of lead (Pb) is 207, while that of helium (He) is 4. Therefore, we can estimate that an atom of lead is about 50 times heavier than an atom of helium.
How many moles are in 2.16 10 to the 24 power atoms of lead?
2.16 X 1024 atoms lead (1 mole Pb/6.022 X 1023) = 3.59 moles of lead ==============
How many atoms are there in 80 grams of lead?
Pb has a MW of 207.2 g/mol. Thus, 80g of Pb is 80/207.2 = 0.39 mol of lead. Using Avogadro's number: (6.0221415 * 1023 atoms/mol)(0.39 mol) = 2.349 * 1023 atoms.
How many atoms in 10 grams of lead?
10 grams lead (1 mole Pb/207.2 grams)(6.022 X 1023/1 mole Pb) = 2.9 X 1022 atoms of lead -----------------------------------
Does a mole of helium gas have the same number of molecules as a mole of lead and why?
No, a mole of helium gas does not have the same number of molecules as a mole of lead. This is because the number of particles in a mole is determined by Avogadro's number, which is approximately 6.022 x 10^23. Since helium is a monoatomic gas and lead is a solid with a lattice structure, the number of helium atoms in a mole is significantly larger than the number of lead atoms in a mole.
What are two atoms that are heavier than carbon?
Elements with atomic numbers 1-5 are lighter than carbon.
How many atoms are in 6.75 multiply by 10 negative 2 moles of mercury?
7.4 x (6.02 x 1023) = 4.4548 x 1024 atoms of mercury. A mole is simply a unit of measurement, like a kilometer or a mile. Just like a kilometer contains 1,000 meters, a mole contains 6.02 x 1023 atoms. Therefore 1 mole of anything, be it mercury atoms, water molecules, or even oranges will always be 6.02 x 1023.
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.
