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
Find the number of moles in 564 grams of copper?
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
Yonas has 44.78 g of copper II sulfate How many moles does he have?
To find the number of moles of copper II sulfate Yonas has, you need to divide the given mass by the molar mass of the compound. The molar mass of copper II sulfate is 159.61 g/mol. 44.78 g / 159.61 g/mol = 0.281 moles of copper II sulfate.
What is the molarity of a solution that contains 55 grams of copper chloride dissolved in 1500 mL of water?
To find the molarity, we first calculate the number of moles of copper chloride using its molar mass. The molar mass of copper chloride is 134.45 g/mol. Then divide the mass by the number of moles and the volume in liters (1500 mL = 1.5 L) to get the molarity. The molarity of the solution is 0.20 M.
How do you calculate the mass of 14.5 moles of copper?
To calculate the mass of 14.5 moles of copper, you would first find the molar mass of copper, which is approximately 63.55 g/mol. Then, multiply the number of moles by the molar mass to get the mass of copper. Therefore, the mass of 14.5 moles of copper would be 922.725 grams (14.5 moles * 63.55 g/mol).

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.
How do you calculate the number of moles in 1.56g of copper II nitrate?
To calculate the number of moles in 1.56g of copper (II) nitrate, you first need to determine the molar mass of copper (II) nitrate. The molar mass of copper (II) nitrate is 187.55 g/mol. Next, divide the given mass by the molar mass to find the number of moles. In this case, 1.56g ÷ 187.55 g/mol ≈ 0.0083 moles of copper (II) nitrate.

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.
What would you need to do to calculate the molality of 0.2kg of nacl in 3kg of water?
To calculate the molality of a solution, you need to know the moles of solute and the mass of the solvent in kilograms. First, calculate the moles of NaCl in 0.2 kg: moles = mass (g) / molar mass. Then, calculate the molality by dividing the moles of solute by the mass of solvent in kg: molality = moles of solute / mass of solvent in kg.
What is the total mass of h2o produced when 32 grams of Cu is completely consumed?
To calculate the mass of water produced when 32 grams of copper is consumed, we need to use the stoichiometry of the reaction. Given the balanced chemical equation for the reaction of copper with water, we can determine the moles of copper reacting and then use the mole ratio to find the moles of water produced. Finally, using the molar mass of water, we can calculate the mass of water produced.
What is the number of moles of copper oxide in 7.95g copper oxide?
To find the number of moles, you need to divide the mass of copper oxide by its molar mass. The molar mass of copper oxide (CuO) is approximately 79.55 g/mol. Therefore, 7.95g of copper oxide is equal to 0.1 moles (7.95g / 79.55 g/mol).
What is the maximum mass of Nitric Acid which would be required to react with 0.35 grams of copper metal?
To determine the maximum mass of nitric acid required to react with 0.35 grams of copper metal, we need to calculate the moles of copper using its molar mass. Then, we use the balanced chemical equation between copper and nitric acid to find the mole ratio between them. Finally, we convert the moles of copper to moles of nitric acid and then to grams. The maximum mass of nitric acid needed can be determined as per the stoichiometry of the balanced chemical equation.
