Answer:
![m_{Cu(NO_3)_2}=2.36 gCu(NO_3)_2](https://tex.z-dn.net/?f=m_%7BCu%28NO_3%29_2%7D%3D2.36%20gCu%28NO_3%29_2)

Hello!
In this case, since the chemical reaction between copper and nitric acid is:
![2HNO_3+Cu\rightarrow Cu(NO_3)_2+H_2](https://tex.z-dn.net/?f=2HNO_3%2BCu%5Crightarrow%20Cu%28NO_3%29_2%2BH_2)
By starting with 0.80 g of copper metal (molar mass = 63.54 g/mol) and considering the 1:1 mole ratio between copper and copper (II) nitrate (molar mass = 187.56 g/mol) we can compute that mass via stoichiometry as shown below:
![m_{Cu(NO_3)_2}=0.80gCu*\frac{1molCu}{63.54gCu} *\frac{1molCu(NO_3)_2}{1molCu} *\frac{187.56gCu(NO_3)_2}{1molCu(NO_3)_2} \\\\m_{Cu(NO_3)_2}=2.36 gCu(NO_3)_2](https://tex.z-dn.net/?f=m_%7BCu%28NO_3%29_2%7D%3D0.80gCu%2A%5Cfrac%7B1molCu%7D%7B63.54gCu%7D%20%2A%5Cfrac%7B1molCu%28NO_3%29_2%7D%7B1molCu%7D%20%2A%5Cfrac%7B187.56gCu%28NO_3%29_2%7D%7B1molCu%28NO_3%29_2%7D%20%5C%5C%5C%5Cm_%7BCu%28NO_3%29_2%7D%3D2.36%20gCu%28NO_3%29_2)
However, the real reaction between copper and nitric acid releases nitrogen oxide, yet it does not modify the calculations since the 1:1 mole ratio is still there:
![4HNO_3+Cu\rightarrow Cu(NO_3)_2+2H_2O+2NO_2](https://tex.z-dn.net/?f=4HNO_3%2BCu%5Crightarrow%20Cu%28NO_3%29_2%2B2H_2O%2B2NO_2)

First, let us define Electronegativity. Electronegativity is "the ability of an atom to attract electrons." In addition, electronegativity increases in elements from left to right, while on the other hand, electronegativity decreases from top to bottom in an element group. It decreases because the atomic radius increases as we go downward an element in the group.
the answer is twenty eight
