Why does a mole of copper atoms weigh less than a mole of lead atoms?
Because copper has a smaller molar mass, hence it will have less mass per mole than lead.
What is the mass in grams of 2x1012 atoms of potassium?
What is the mass, in grams, of 2 × 1012 atoms of potassium?
What does adding s neutron to an atoms nucleus do to the atoms mass?
Increases it by one mass unit.
What are mass of unstable atoms?
Unstable atoms are said to be radioactive
How many Atoms are in a pound of lead?
I assume you mean pure Lead, and I'm here to tell you that Lead is an element in the periodic table. The fact that it is an element means that it is only 1 type of atom; Lead! The atomic symbol for Lead is Pb.
Why does a mole of copper atoms weigh less than a mole of lead atoms?
Because copper has a smaller molar mass, hence it will have less mass per mole than lead.
What has a greater mass 2 atoms of lead or 5.1 X 10-23 mole of helium?
The weight is greater for 2 atoms 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
Will kilogram of hydrogen contain more atoms then kilogram of lead?
Yes, because each hydrogen atom has less mass than each lead atom.Yes, because each hydrogen atom has less mass than each lead atom.Yes, because each hydrogen atom has less mass than each lead atom.Yes, because each hydrogen atom has less mass than each lead atom.
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 Helium-atoms and Carbon-atoms do you have if you have He-atoms with mass of 40amu and C-atoms with mass of 120amu?
Mass of 1 Helium atom is 4 amu and mass of 1 Carbon atom is 12 amu. So there are 10 helium atoms and 10 carbon atoms
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 atoms in lead oxide?
There are 6 atoms in dioxide lead because there 1 hydrogen atom and 5 nitrogen atoms
What Make up 50 percent of the atomic mass of the nucleus?
Well, this is not exact, but smaller atoms have about the same number (and mass) of neutrons and of protons. Heavier atoms have a larger percentage of their mass in neutrons.Well, this is not exact, but smaller atoms have about the same number (and mass) of neutrons and of protons.

Is fusion nuclear decay or nuclear synthesis?
Fusion is nuclear synthesis, combining atoms of lesser mass into atoms of greater mass. Decay is reducing the mass of larger (unstable) atoms to form atoms of lesser mass.
What is the mass of lead?
Lead (Pb) has the atomic number 82 with an Atomic Mass of 207.2 amu.
