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.
Why is one mole of aluminum larger than one mole of copper?
It isn't. The mass of one mole of aluminum is less than the mass of one mole of copper. The number of atoms in one mole of aluminum is the same as the number of atoms in one mole of copper, which is 6.022 x 1023, also known as Avogodro's number.
Is the mass of 0.50 mole of copper is 32 grams?
True.
What is the mass of one mole of copper?
63.55 g/mol (63.55 grams per mole)
Which has more mass iron or copper?
Iron has an atomic number of 26. The atomic number of Copper is 29. Therefore, the largest mass would be Copper if you had a single mole of each substance.

True.
What is the mass in grams of one atom of copper?
The periodic table states that the molar mass of copper is 63.546 grams per mole. That means that if you have one mole of copper, it will weigh 63.546 grams. One mole is 6.022x1023 (Avogadro's number) atoms. To find the mass of one copper atom in grams, you simply divide copper's molar mass by the number of atoms in one mole. 63.546 / 6.022x1023 = 1.055x10-22 One atom of copper weighs 1.055x10-22 grams.
What is the mass of one mole of copper?
63.55 g/mol (63.55 grams per mole)
What is the mass of a molecule of copper oxide?
1 molecule copper oxide (1 mole CuO/6.022 X 10^23)(79.55 grams/1 mole CuO) = 1.32 X 10^-22 grams Or, if you meant molecular mass........ 79.55 grams/mole
Which has more mass iron or copper?
Iron has an atomic number of 26. The atomic number of Copper is 29. Therefore, the largest mass would be Copper if you had a single mole of each substance.
What the molar mass for copper?
Atomic mass of Cu is 63.55 a.m.u. , 63.55 g/mole(Cu is an element, not a molecule)
How do you calculate the mass of 14.5 moles of copper?
1 mole of Copper has a mass of 63.546 g. So, 14.5 moles will be 14.5 times that amount. Do the math.
How do you convert 2.11x10 to the 24 atoms of copper to mass in grams?
2.11x10^24 atoms... Divide by Avogadro's Constant (6.02x10^23 particles/mole) Gives you moles of copper... Multiply by the molar mass of copper. (?? g/mol) Gives you grams of copper...
What is the mass of 19 atoms of copper in grams?
Not much! 19 atoms Cu (1 mole Cu/6.022 X 1023)(63.55 grams/1 mole Cu) = 2.0 X 10-21 grams of copper ---------------------------------------
How many copper atoms are in a pure copper statue with a mass of 133 kg?
A lot! 154 kg copper (1000 grams/1 kg)(1 mole Cu/63.55 grams)(6.022 X 1023/1 mole Cu) = 1.46 X 1027 atoms of copper ---------------------------------------
