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.
400 grams of nickel sulphate (anhydrous) is equivalent to 2,58 moles.
871 grams
To convert grams into atoms, you have to convert them into moles first. Get the molar mass and multiply it by the number of moles to get the atoms.
2.83 moles
The white copper sulphate will become blue. This is because copper sulphate usually has 5 moles of H2O, but it has reached a temperature where all five moles will have detached themselves from the copper sulphate, so it will become anhydrous (without water) and white. Then, when water is added back to it, it returns to its original blue state.
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 answer is 1,54 moles.
2.11x10^24 atoms... Divide by Avogadro's Constant (6.02x10^23 particles/mole) Gives you moles of copper... Multiply by the molar mass of copper. (?? g/mol) Gives you grams of copper...
