Answer:
11.7 g in 1 L of water.
Explanation:
Molarity (M) or Molar concentration is a measure used in chemistry for solutes in a solution.
It is defined as mol/ L (number of moles per litre).
0,2 M means we have 0,2 mol/ L
In order to know how many grams this means we need to look up the molecular weight of the solute. In this case NaCl: 58.443 g/mol
=
X=
X= 11.69 g
The solution has 11.69 g of NaCl in 1 L of water since its an adequate polar solvent for NaCl dissolution.

Atomic waste is one of the most troublesome sorts of waste to oversee on the grounds that it is profoundly dangerous. As indicated by the U.S. Ecological Protection Agency (EPA), atomic waste is arranged into six general classes.
[1-2] These incorporate (1) spent atomic fuel from atomic reactors, (2) uranium factory tailings from mining and processing of uranium mineral, (3) significant level waste from spent atomic fuel reprocessing, (4) low-level waste, (5) transuranic waste from guard projects, and (6) normally happening and quickening agent created radioactive materials.
The well-being concerns and security issues related with atomic waste present significant limitations on the far reaching utilization of atomic vitality. Because of its b and exceptionally perilous properties, atomic waste is required to be deliberately put away or reprocessed. The putting away and reprocessing are additionally convoluted by the long half existence of the radioactive materials in the atomic waste.
For instance, a portion of the segments can remain half of their hazardous levels even one million years after the fact after generation.

This is usually because when they first became fossils, they embedded into the ground. Over many years afterwards, more layers came to cover that layer and so on. Newer fossils would be embedded into newer layers. That's why the older ones tend to be found the deeper you look.
Answer: Well probably because of the fact that over time the rocks stack up on top of each other because of weathering and erosion and as they stack they get deeper and deeper, so fossils that were at the top one time will slowly sink as the time progresses.
