Answer:
The answer to the question is;
The concentration of the Solution #1 in terms of molarity is
0.16704X moles/litre.
Explanation:
Let the concentration of the stock solution be X moles/liter
Therefore, 83.52 ml of the stock solution contains
83.52×(X/1000) moles
Dilution of 83.52 ml of X to 500 ml gives solution 1 with a concentration of
500 ml of solution 1 contains 83.52×(X/1000) moles
Therefore 1000 ml or 1 litre contains 2×83.52×(X/1000) moles = 0.16704X moles/litre
The molarity of solution 1 is 0.16704X moles/litre.
Answer:
A, B, and C are the correct answers.
Explanation:
The reason why solid, liquid, and gas are the most common of the elements because usually in school they teach you more about those 3 elements more than plasma ( from where I am ). Also, all of these states behave differently. Liquid is a substance that flows freely but is of constant volume, having a consistency like that of water or oil. Solid is firm and stable in shape. And gas is an air like substance. I'm not sure how to explain this more, it sounded better in my head. Hope this helped though!
Moles of SF6 = 0.15/molar mass of SF6 = 0.15/146.06 = 1.02 x 10⁻³ moles.
Moles of NH3 = Moles of SF6 = 1.02 x 10⁻³ moles.
Therefore mass of NH3 = moles of NH3 x molar mass of NH3
= 1.02 x 10⁻³ x 17.03
= 0.017 grams.
Most metals are good conductors of heat and they are solids at room temperature.
I believe t<span>he technique of separation employed to purify an organic solid that may be contaminated by impurities is called recrystallization.
It works by putting your solid in a container with some liquid, then boiling out the contaminants.</span><span />
