Answer:

The mass percent refers to the mass of an element in a compound. It is one of the ways of expressing concentration. The mass percent of the solution provides the percentage of the amount of solute present in grams of solution.

The mass percentage of S=40.06 % and the molar mass of S= 32. By applying the formula of mass percent,we can calculate the molar mass of M.

The molar mass of M=159.76-64=95.76

We know that the element of molybdenum has molar mass of 96. Therefore, the element M is <u>Molybdenum.</u>

Calculate the mass percent (m/m) of a solution prepared by dissolving 51.56 g of NaCl in 164.2 g of H2O. Express your answer to

denis-greek [22]

Answer:

"23.896%" is the right answer.

Explanation:

The given values are:

Mass of NaCl,

= 51.56 g

Mass of H₂O,

= 165.6 g

As we know,

⇒ Mass of solution = $Mass \ of \ (NaCl+H_2O)$

= $51.56+164.2$

= $215.76 \ g$

hence,

⇒ $Mass \ percent =\frac{Mass \ of \ NaCl}{Mass \ of \ solution}\times 100$

$=\frac{51.56}{215.76}\times 100$

$=23.896 \ percent$

Hydroelectric power is produced using the energy of moving water. Which description tells how this process is accomplished? Wate

Ad libitum [116K]

The correct answer is; Water flowing downstream is held up in a reservoir behind a dam. Some water moves down channels through turbines connected to generators which produce electricity.

Further Explanation:

Hydroelectric power is being used more in recent times than in the past. Hydroelectric power is a more cleaner energy source than the coal plants that produce electricity.

Hydroelectric power plants are built within a dam system and uses the water as source of energy. The water goes into channels created that hits the turbines, the turbines are then moved around by the water and these are connected to the large generators and this produces electric. There are many new hydroelectric plants being built. One of the newest hydroelectric power plants is located in Pella, Iowa.

Which one of the following characteristics indicates the presence of weak intermolecular forces in a liquid?A) none of the above

grin007 [14]

Answer:

C) a low heat of vaporization.

Explanation:

It is C) a low heat of vaporization.

Low heat of vaporization means less amount of energy is required to vaporize a liquid. This further means the liquid has weaker intermolecular force of attraction that is why on provide lesser heat only it vaporizes.

Low vapor pressure, high boiling point and high critical temp. all contribute to strong intermolecular forces in a liquid
