Answer: 1.0 × 10-14
Explanation:
Pure water, represented as
H2O --> [H+] + [OH -]
undergoes a reversible reaction in which both H+ and OH- are generated.
The equilibrium constant for this reaction, called the water dissociation constant, Kw, is 1.0 × 10-14 at 25 °C.
Answer:
Permanent Magnets are always magnetic.
Temporary Magnets loose their magnetizing power after the source is removed. (outside a magnetic field)
Electromagnets are made by sending electric coil around an iron rod. (I.e. Nail, coil, and batteries can pick up paperclips)

Hey there!
Volume in mL :
1.25 * 1000 => 1250 mL
Density = 0.921 g/mL
Therefore:
Mass = density * volume
Mass = 0.921 * 1250
Mass = 1151.25 g
