What element has a atomic mass of 64.546?
copper
The copper cube had a mass of 2.7g and the volume of the copper cube is 1cm to the 3rd power?
this means that copper is 2.7g/cm3
Avogadros number of phosphorus P atoms would have a mass of?
By saying Avogadro's number of atoms, you are saying one mole (or 6.02 × 1023 atoms). And one mole of any elements is its atomic mass. Phosphorus' atomic mass is 31.0 grams
When calculating an atoms approximate mass how is the mass of electrons figured?
electrons are the same as protons
How many copper atoms are in a pure copper statue with a mass of 148kg?
To find the number of copper atoms in the statue, you need to first determine the number of moles of copper using its molar mass. Then, you can multiply the number of moles by Avogadro's number to find the number of atoms. Given that the molar mass of copper is approximately 63.55 g/mol, you can follow these steps to calculate the number of copper atoms in the statue.
How many copper atoms are in a pure copper statue with a mass of 133 kg?
To calculate the number of copper atoms in the statue, you first need to find the moles of copper present in 133 kg using its molar mass. Then, you can use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles of copper to atoms.
If you have 1.20 and times 1024 atoms of copper how many moles of copper do you have?
To find the number of moles of copper, we first need to calculate the total mass of copper in the sample. Copper has an atomic mass of 63.55 g/mol. The total mass of the sample is 1.20 g x 1024 atoms = 1228.8 g. Next, we convert this mass to moles by dividing by the atomic mass of copper: 1228.8 g / 63.55 g/mol = 19.36 moles of copper.
What mass of copper contains the same number of atoms as 68.7 g of iron?
To find the mass of copper containing the same number of atoms as 68.7 g of iron, we need to first calculate the number of atoms in 68.7 g of iron using its molar mass. Then, we convert this number of atoms to copper atoms using the ratio of their molar masses. Finally, we determine the mass of copper corresponding to this number of atoms.
How many copper atoms are in 2.36 of copper?
To find the number of copper atoms in 2.36 g of copper, first convert the mass to 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. So, there are approximately 2.36 x 6.022 x 10^23 atoms of copper in 2.36 g.
How many S atoms are there in 120.0g of Copper(II)Sulfate?
There are 3 moles of S atoms in 120.0g of Copper(II) Sulfate. In one mole of Copper(II) Sulfate, there are 4 moles of oxygen atoms, 1 mole of sulfur atoms, and 1 mole of copper atoms. Since the molar mass of Copper(II) Sulfate is 159.61 g/mol, the molar mass of sulfur is 32.065 g/mol. Hence, there are 3 moles of sulfur atoms in 120.0g of Copper(II) Sulfate.
A sample of copper with a mass of 63.5 g contains 6.02x1023 atoms calculate the mass of the single copper?
17.48 atoms
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 atom in 6.35 g of copper?
To find the number of atoms in 6.35 g of copper, you first need to determine the number of moles of copper present by dividing the mass of copper by its molar mass (63.55 g/mol). Then, you can use Avogadro's number (6.022 x 10^23 atoms/mol) to find the number of atoms in that number of moles.
How many grams are there in 2.20 x 1024 atoms of copper?
The molar mass of copper is 63.55 g/mol. To find the mass of 2.20 x 10^24 copper atoms, first calculate the number of moles by dividing the number of atoms by Avogadro's number (6.022 x 10^23). Then, multiply the moles by the molar mass of copper to get the mass in grams.
What is the mass of 19 atoms of copper in grams?
To calculate the mass of 19 atoms of copper in grams, you need to determine the molar mass of copper. The molar mass of copper is approximately 63.55 grams per mole. Then, you can use Avogadro's number (6.022 x 10^23 atoms per mole) to convert atoms to grams. So, the mass of 19 atoms of copper would be 19*(63.55/6.022e23) grams.
How many atoms are in a 1cm of copper wire and who calculate this?
The number of atoms in a 1cm length of copper wire can be calculated using Avogadro's number, which is approximately 6.022 x 10^23 atoms per mole. The molar mass of copper is around 63.55 g/mol, so you would find the mass of copper in 1 cm of wire and then convert that to moles to determine the number of atoms.
