Answer:
E. (None of these).
It is 0.333 M.
Explanation:
A molar solution would contain 183 g in 1 liter.
By proportion, this solution contains 18.3 * 1000/300
= 61 g per liter.
So it is 61 / 183 = 0.333 M.
The source below says 35.89g of NaCl dissolve in 100 g of water at 20 °C.
<span>(35.89g / 100 mL) x (2000 mL) = 718 g

Answer:
2-
Explanation:
For an element to be stable, it must follow the octet rule: an atom will gain, lose or share electrons until its valence shell is complete with 8 electrons.
An element with the valence electron configuration ns²np⁴ has 6 (2+4) electrons in its valence shell. Thus, in order to fulfill the octet, it will gain 2 electrons. As a consequence, it will form an anion with charge 2-.
Answer:
You need to add 400mL of water
Explanation:
500mL = 5 M HCI That means that if you divide both sides by 5
100mL = 1 M HCI If you need ot get rid of 4 M HCI then you add 400 mL of water because that is what it is equal to
