What is the atomic mass of the element Cu?
The atomic mass of Cu (Copper) is 63.546 amu (atomic mass unit).
What is the molecular mass of the copper nitrate produced from the complete reaction of 45.6 g of copper according to the chemical reaction shown?
Since the question is about molecular mass, the weight of the reactant copper (45.6 g) is not determining the answer.There are three possible copper nitrate products:Cu(I) nitrate, CuNO3 molecular mass is 125.5509 g.mol-1Anhydrous Cu(II) nitrate, Cu(NO3)2 : molecular mass is 187.5558 g.mol-1Cu(II) nitrate-trihydrate, (Cu(NO3)2).(3H2O) : molecular mass is 241.60 g/mol
How many moles of CuNO32 are produced when 3 moles of Cu react?
The answer is 3 moles of Cu)NO3)2..
What is the atomic mass of Cu?
Copper is a metal element. Atomic mass of it is 64.
How many moles of Cu(NO3)2 are produced when 3 moles Cu react?
When 3 moles Cu react 3 moles of copper nitrate are obtained.
What is the total mass of h2o produced when 32 grams of Cu is completely consumed?
18 grams
What is the atomic mass of the element Cu?
The atomic mass of Cu (Copper) is 63.546 amu (atomic mass unit).
What is being produced when Zn plus CuCl2 equals Cu plus ZnCl2?
Cu and ZnCl2 are being produced.
What has the larger atomic radius Cu or Cl2?
The atomic mass of Cu is: 63.546 g.mol The atomic mass of Cl2 is: 35.453 g.mol So your answer would be: Cu has the largest Atomic mass.
What the molar mass for copper?
Atomic mass of Cu is 63.55 a.m.u. , 63.55 g/mole(Cu is an element, not a molecule)
What is the mass of 7.00ml of copper?
You need to know the density of copper, which is 8.96 g/cm3 at room temperature. Density = mass/volume. To solve for mass, the equation is manipulated so that mass = density x volume. 1mL = 1cm3, so 7.00mL Cu = 7.00cm3 Cu. Mass = 8.96g/cm3 x 7.00cm3 Cu =62.7g Cu
Is the percent by mass of copper in CuSO4 5H2O the same as in CuSO4?
No. The % of Cu by mass in CuSO4 will be greater than the % of Cu by mass in the pentahydrate (5H2O) because in the hydrate there is added mass (5 H2O = 90 g) but no added Cu.
What is the maximum amount of Cu that could be produced by reacting 20.0 grams of Al with excess CuSO4?
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
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

Is hydrogen produced when copper reacts with silver nitrate?
No, the reaction is: 2AgNO3+Cu=Cu(NO3)2+2Ag
How many moles of CuNO32 are produced when 3 moles of Cu react?
The answer is 3 moles of Cu)NO3)2..
