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

Copper is a transition element used in the making of coins calculate the mass in grams of 0.0420 moles of copper?
To calculate the mass of copper in grams, you first need to find the molar mass of copper, which is approximately 63.55 g/mol. Then, multiply the number of moles (0.0420 moles) by the molar mass to get the mass in grams. Mass = moles x molar mass Mass = 0.0420 moles x 63.55 g/mol = 2.67 grams of copper.
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 Na are in 42 grams of Na?
To find the number of moles of Na in 42 grams, we can use the molar mass of Na, which is approximately 23 grams/mol. First, calculate the number of moles by dividing the given mass by the molar mass: 42 grams / 23 grams/mol = 1.83 moles of Na.

How many moles are in 20.0 grams of NaCl?
For this you need the atomic (molecular) mass of NaCl. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. NaCl=58.5 grams20.0 grams NaCl / (58.5 grams) =.342 moles NaCl
What is the mass of copper if it contains same number of atoms as present in 3.2 grams of sulphur?
To find the mass of copper containing the same number of atoms as in 3.2 grams of sulfur, we first determine the number of moles of sulfur. Sulfur has a molar mass of approximately 32 g/mol, so 3.2 grams corresponds to 0.1 moles of sulfur. Since copper (Cu) has a molar mass of about 63.5 g/mol, the mass of copper that has the same number of moles (0.1 moles) is calculated as 0.1 moles × 63.5 g/mol = 6.35 grams. Therefore, the mass of copper is 6.35 grams.
What is the weight in grams of 0.252 moles of copper?

How many electrons in 2.9 grams of copper?
i havent got an elements table in front of me but here is how you do it: figure out how many moles is 2.9 grams of copper by using molecular wieght, then simply multiply so: No of moles* No of atoms in one mole* number of electrons in one atom of copper (which is the same as the No of protons...)
How many grams are there in 3 moles of CuSO4?
The molar mass of CuSO4 is 159.6 g/mol. To find the mass of 3 moles of CuSO4, multiply the molar mass by the number of moles: 3 moles * 159.6 g/mol = 478.8 grams. Therefore, there are 478.8 grams in 3 moles of CuSO4.
How do you calculate the mass of 14.5 moles of copper?
