Answer:
Arranged in order of most soluble to least soluble in water:
Explanation:
Water is a polar solvent due to the electric charge it possesses. Hence it would only dissolve polar molecules.
Non-polar molecules would be dissolved by non-polar solvents.
Short chain alcohols are more soluble than butanol, but generally the polar -OH group is soluble in water.
Answer:
0.1186mol Hg
Explanation:
To calculate the number of moles using the mass we divide the mass by the molar mass.
23.79g ÷ 200.59g/mol = 0.1186mol Hg
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:
Matter is the term for any type of material. Matter is anything that has mass and takes up space. At a minimum, matter requires at least one subatomic particle, although most matter consists of atoms.
Some examples are: Water, books, pencils, sun, earth, moon, electron, proton, mesons, and quarks
