1- Find Copper molar mass (from Periodic Table) 63.55
2- Calculate using dimensional analysis
564g of Cu ( 1 mol Cu )
----------------( 63.55 g Cu ) = 8.87 mol Cu
** divide 564 by 63.55
gram units cancelled and you are left with moles
** Don't forget to consider the significant figures

Calculate the mass in grams of 0.0420 moles of copper?
You are given moles and need to find grams, the atomic mass of any element is in g/mol so just go to the periodic tables and Cu which is copper has a mass of 63.546 grams/ mole. Then you know if you multiply Mole * g / mol the moles will cancel out and you will be left with grams so .0420 mol Cu * 63.546 g / mole Cu = 2.669 grams
How many moles of copper are present in 75.92 g?
The atomic mass of Copper is 63.5 grams One mole of any element has a mass equal to the atomic mass. 0.75 grams of Cu = x moles of Cu 63.5 grams of Cu = 1 mole of Cu Set up a proportion and solve for x Divide 0.75 / 63.5 = x /1 0.75 ÷ 63.5 = x
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.
How many moles of carbon dioxide are in 211 g of carbon dioxide?
Add the atomic weights of one C atom and two O atoms.That's the number of grams in one mole.Use division to find the number of moles in your 211 g.
How do you find the number of moles of hydrogen there are in 3.5 moles of NH42 CO3?
The answer is 14,115 moles.
How do you find the number of moles that will react with 5 grams of butane?
We need to know the number of moles of WHAT is to react with the butane to provide you with an answer.
0.871 moles is how many grams?
Multiply the number of moles by the molecular weight of the compound (or atomic weight for an element) to find the mass in grams.
How many moles grams are in 24.6 moles of Fe?
Find iron (Fe) on the periodic table the biggest number (at the bottom) is the mass number 1 mole is that number in grams. you can work it out from there.
How many moles are in 89.0 grams of aluminum?
all you have to do to fine the moles of any element is divide the given grams by the molar mass (which you can find on a periodic table of elements) Likewise, if you need to find the grams, just multiply the number of moles by molar mass. moles = grams/molar mass grams = moles x molar mass your equation should look like this: moles = 89.0 / 17.0 moles = .471
Calculate the mass in grams of 0.0420 moles of copper?
You are given moles and need to find grams, the atomic mass of any element is in g/mol so just go to the periodic tables and Cu which is copper has a mass of 63.546 grams/ mole. Then you know if you multiply Mole * g / mol the moles will cancel out and you will be left with grams so .0420 mol Cu * 63.546 g / mole Cu = 2.669 grams
How many moles are in 57 grams of Xenon?
To find the number of moles in 57 grams of Xenon, divide the given mass (in grams) by the molar mass of Xenon. The molar mass of Xenon is 131.3 grams/mol. Therefore, 57 grams of Xenon is equal to 0.434 moles (57/131.3).
What is the number of moles of argon in 607 g of argon?
the equation is Xg multiplied by the moles/grams of X = moles of X (the grams cancel leaving you with moles) 607g Ar x 1 mole/ 39.95g = 15.19 moles
How many grams does 5.60 x 1022 molecules of SiO2?
To find the mass, we divide by Avogadro's number to find the amount of moles. We then multiply the moles by the molar mass of the compound which is 60.08 grams. Doing all of this, we get a mass in grams of 5.59 grams.

Which has more atoms 6.35 g of copper or 0.1 mol of copper?
Find the number of moles that 6.35 g of copper is. Copper's molecular weight is 63.55 g/mole 6.35g /63.55 g/mol = .0999 moles Now, my guess is this question is all about significant figures. It appears as though your teacher wants you to say "they have the same number of atoms" because .0999 moles, when you take into significant figures, is .1 moles. So .1 moles and .1 moles have the same number of atoms. So that's what my answer would be.
How many moles of copper are present in 75.92 g?
The atomic mass of Copper is 63.5 grams One mole of any element has a mass equal to the atomic mass. 0.75 grams of Cu = x moles of Cu 63.5 grams of Cu = 1 mole of Cu Set up a proportion and solve for x Divide 0.75 / 63.5 = x /1 0.75 ÷ 63.5 = x
How much space will 2.3 grams of sulfur dioxide take up at standard temperature and pressure?
we first find the number of moles( number of moles= mass/molar mass). the we can find the volume by using the formule( volume=number of moles multiplyd by the molar volume)
