It is from least to greatest
Answer:
92.46 g
Explanation:
The reaction is
I = Current = 19.5 A
t = 4 hours =
F = Faraday constant = 96485.33 C/mol
Molar mass of copper = 63.546 g/mol
Charge is given by
Moles of electrons is given by
Moles of copper is
Mass of copper would be
The mass of copper electroplated is 92.46 g.
Answer:
I think sodium it may be wrong soŕry
I think the product would be: Mg(NO3)2 + Ni
Molality can be expressed by moles of solute over
kilograms of solvent. The question asks the molality of 0.25m NaCl. 0.25m NaCl
is equal to 0.25 moles of NaCl over 1 kg of water.
