Divide 5.58 by the Atomic Mass of Copper
Then Multiply by 6.022x10^23
Then Multiply by the number of protons of Copper.
5.58/63.55=.087805,
.087805x(6.022x10^23)=5.28761x10^22
5.28761x10^22 x (29) = 1.53341x10^24 Protons

How many MOLES of sodium nitrate are present in 2.85 grams of this compound ?
234 grams :)
One atom. It contains 29 protons in its nucleus with 29 electrons orbitting. Hence copper (Cu) having the atomic number 29.
63.4g
3.18 grams copper (1 mole Cu/63.55 grams)(6.022 X 10^23/1 mole Cu) = 3.01 X 10^22 atoms of copper there are 29 protons in one atom of copper, so............... 29 * 3.01 X 10^22 = 8.73 X 10^23 protons in 3.18 grams of copper
An atom of copper has 29 protons.
6.81 grams copper (1 mole Cu/63.55 grams)(6.022 X 1023/1 mole Cu) = 6.45 X 1022 atoms of copper ----------------------------------------
26 protons
Copper has 29 Protons
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...)
Copper has 29 electons,29 protons,and 35 neutrons.
Copper has 29 protons, that is why it has the atomic number of 29. In addition, copper has 29 electrons and 35 neutrons.
16.
There shouldn't be any copper in eight grams of gold! Unless it's a copper/gold alloy.
29 protons and 27electrons are present in Cu2+ ion.
