Which would have a higher mass a mole of K atoms or a mole of Au atoms?
A mole of Au
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.
Which would contain more atoms a mole of K atoms or a mole of Au atoms?
Let's see. 1 mole K atoms = 6.022 X 1023 atoms * 19 electrons = 1.144 X 1025 electrons in one mole potassium ------------------------------------------------------------- 1 mole Au atoms = 6.022 X 1023 atoms * 79 electrons = 4.757 X 1025 electrons in one mole gold ------------------------------------------------------ A mole of gold, Au, atoms contains more electrons than a mole of potassium, K, atoms.
What would 117 sodium atoms weigh?
1 mole of sodium weights 23g 1 mole of sodium = 6.02 x 10^23 atoms = 23g 117 atoms = ? 117 x 23 / 6.02 x 10^23 (should be a very small number)
Which would contain more electrons a mole of K atoms or a mole of Au atoms?
Let's see. 1 mole K atoms = 6.022 X 1023 atoms * 19 electrons = 1.144 X 1025 electrons in one mole potassium ------------------------------------------------------------- 1 mole Au atoms = 6.022 X 1023 atoms * 79 electrons = 4.757 X 1025 electrons in one mole gold ------------------------------------------------------ A mole of gold, Au, atoms contains more electrons than a mole of potassium, K, atoms.
How do you show the amount of heat released on formation of one mole of helium atoms and one mole of neutrons from two moles of deuterium atoms equals 3.14x108 using the equation Emc2?
Rawr
If you knew how many atoms of gold you had how could you figure out what the sample would weigh on a scale?
Yes. One mole (6.02 x 10 to the 23 atoms) would weigh 197 grams.
Which would have a higher mass a mole of K atoms or a mole of Au atoms?
A mole of Au
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.
How is the mole of a hydrogen the same asa mole of helium?
1 mole of all elements has 6.023 x 1023 atoms (but one mole of each element will weigh different)
Which would contain more atoms a mole of K atoms or a mole of Au atoms?
Let's see. 1 mole K atoms = 6.022 X 1023 atoms * 19 electrons = 1.144 X 1025 electrons in one mole potassium ------------------------------------------------------------- 1 mole Au atoms = 6.022 X 1023 atoms * 79 electrons = 4.757 X 1025 electrons in one mole gold ------------------------------------------------------ A mole of gold, Au, atoms contains more electrons than a mole of potassium, K, atoms.
What would 117 sodium atoms weigh?
1 mole of sodium weights 23g 1 mole of sodium = 6.02 x 10^23 atoms = 23g 117 atoms = ? 117 x 23 / 6.02 x 10^23 (should be a very small number)
What would have the greatest mass 1 mole of iron atoms 2 moles of oxygen atoms 4 moles of carbon atoms or 1 mole of potassium atoms?
1 mole of iron atoms has the greatest mass - 55,845 g.
Which would contain more electrons a mole of K atoms or a mole of Au atoms?
Let's see. 1 mole K atoms = 6.022 X 1023 atoms * 19 electrons = 1.144 X 1025 electrons in one mole potassium ------------------------------------------------------------- 1 mole Au atoms = 6.022 X 1023 atoms * 79 electrons = 4.757 X 1025 electrons in one mole gold ------------------------------------------------------ A mole of gold, Au, atoms contains more electrons than a mole of potassium, K, atoms.
A mole of uranium atoms and a mole of hydrogen atoms would both?
d. contain 6.02 x 1023 particles
Does a mole of neon atoms weigh the same as a mole of aluminum atoms?
No. Think of it this way - say you had 20 basketballs and 20 bowling balls. Will the basketballs weigh the same as the bowling balls? No, because an individual basketball weighs less than a bowling ball, so if you have equal numbers of them, they aren't going to weigh the same. Now take 6.02 × 1023 atoms (one mole) of neon and 6.02 × 1023 atoms of aluminum. One atom of neon is going to weigh less than one atom of aluminum, so equal numbers of them aren't going to weigh the same.
How many atoms are in 8.25 mole of chromium?
1 mole = 6.022e23 atoms 8.25 mole = 4.96815 e 24 atoms
