Answer:
The answer to your question is: 58.4 g of NaCl
Explanation:
Data
Volume = 200 ml = 0.2 l
Concentration = 5M
MW = 58.4 g
mass NaCl = ?
Formula
Molarity = (# of moles ) / volume
# of moles = Molarity x volume
# of moles = 5 x 0.2
# of moles = 1
58.4 g ---------------------- 1 mol
x --------------------- 1 mol
x = (1 x 58.4) / 1
x = 58.4 g of NaCl
Answer:
b. 17,190
Explanation:
Using the formula for C-14 dating,
where Present Value N =1/8 of Parent Sample
Initial Value, 
=1
Half Life, 
=5730 years
=17,190
Therefore the fossil is about 17190 years old.

Answer:
Water moves from the ground or oceans into the atmosphere through a process called evaporation. It's a process that happens on a molecular level when the molecules of water are really energized and rise into the air. Now you've got water in the air and water on land. Organisms all over the Earth need water to survive.
