Copper(II) sulfate contain 398,1339 g copper in 1 kg CuSO4.
1654 grams exactly
A lot! 154 kg copper (1000 grams/1 kg)(1 mole Cu/63.55 grams)(6.022 X 1023/1 mole Cu) = 1.46 X 1027 atoms of copper ---------------------------------------
The mass of 25 kg of anything is precisely 25 kg (25,000 grams).
