The mass of 254 mL of water is 254 g. Since the density of water is 1g/mL, we can simply multiply the density 1g/mL by 254 mL of water and get 254 g as our answer. Since mL is in the numerator and denominator, mL cancels out and we are left with g only.
They all have the same number of electrons in the electron cloud.

Answer:
a.Cathode rays have mass.
b.They are subatomic size particles in an atom.
d. Matter contains negative charge and by inference positive charge.
e. Particles of the cathode rays are fundamental to all matter.
Explanation:
The statements above reflect the Thompson model of the atom. Electrons were first known as cathode rays. The Thompson's model viewed the atom as a sphere of negative charges into which positive charges were embedded. This is the plum pudding model of the atom.
