Answer:
When an atom gains/loses an electron, the atom becomes charged, and is called an ion. Gaining an electron results in a negative charge, so the atom is an anion
Answer:
Water has a molar mass of 18.015 g/mol . This means that one mole of water molecules has a mass of 18.015 g . So, to sum this up, 6.022⋅1023 molecules of water will amount to 1 mole of water, which in turn will have a mass of 18.015 g . 2.7144moles H2O ⋅6.022⋅1023molec.

A. Linear Relationships
x 2 4 6 8 10 12
y 4.4 8.8 13.2 17.6 22 26.4
(you can plot this by using the (x,y) coordinates for each pair above.)
B. y=2.2x
mass is 2.2 times larger than the volume.
C. The mass is 2.2 times the volume.
