Well, darling, if you want to find the moles of Cu in 2 grams of CuSO4.5H2O, you first need to calculate the molar mass of CuSO4.5H2O. Then, you divide the mass of Cu by the molar mass to find the moles. So, in this case, you would divide 2 grams by the molar mass of Cu to get the moles of Cu. Easy peasy lemon squeezy.
To determine the number of grams of Cu(NO3)2 produced, you need to consider the molar ratio between Cu(NO3)2 and Cu. Firstly, convert the 4.2 grams of Cu to moles using the molar mass of Cu. Then, use the balanced chemical equation to find the moles of Cu(NO3)2 produced. Finally, convert the moles of Cu(NO3)2 to grams using its molar mass.
find moles: 20.0 grams of Al @ (27.0 g/mol) = 0.7407 moles of Al by the reaction: 2 moles Al+3CuSO4 → Al2(SO4)3 +3 moles Cu 0.7407 moles of Al produces 3/2 's as many moles of Cu = 1.11 moles of Cu find mass, using molar mass: 1.11 moles of Cu @ (63.5 g/mol) = 70.6 grams of Cu your answer is 70.6 g
Multiply 564 grams of copper by 1 mole over the atomic mass of copper (represented in grams). 564 g Cu * 1 mol Cu / (atomic mass) g Cu The atomic mass is located on the periodic table and represented in atomic units. The same value is used here, but with the unit as grams.
1 mol of an element is equal to it's atomic weight, but with grams instead of amu (or daltons) as the unit. For example, with copper (Cu), 63.5 amu is its rough atomic weight, which means it weighs roughly 63.5g per mol. Then we just need to divide through. 63.5 x 0.345 = 21.9g
The balanced equation for the reaction is: Cu + 2AgNO3 -> Cu(NO3)2 + 2Ag Calculate the molar mass of Cu and Ag (Cu = 63.55 g/mol, Ag = 107.87 g/mol). Using the molar ratio of Cu to Ag (1:2), convert the mass of Cu to moles, then use the molar ratio to find the moles of Ag produced. Finally, convert moles of Ag to grams using the molar mass of Ag to find the grams of silver produced.
4,5 moles of copper are equivalent to 285,957 g.

For this you need the atomic mass of Cu. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel.2068 grams Cu / (63.5 grams) = 32.6 moles Cu
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

When 3 moles Cu react 3 moles of copper nitrate are obtained.
This depends on: - if it is an anhydrous or hydrated salt - if it is a salt of Cu(I) or Cu(II) For CuSO4(anh.) the answer is 0,00364 moles.
The answer is 3 moles of Cu)NO3)2..
To determine the number of molecules in 122 grams of Cu(NO3)2, you need to first calculate the number of moles of Cu(NO3)2 using its molar mass. Then, you can use Avogadro's number (6.022 x 10^23) to convert the moles of Cu(NO3)2 to molecules.
