What class of organism is vital in the recycling of nutrients in the ecosystem?

A piece of tin has a mass of 16.52 g and a volume of 2.26 cm3 what is the density of tin?

boyakko [2]

Answer:

The density of tin is 7.31 g/cm³.

Explanation:

Given that the formula of density is D = m/v where m represents mass and v is volume :

D = 16.52/2.26

D = 7.31 g/cm³ (3sf)

Answer: The correct answer is A. Molality. It is the concentration expressed as moles of solute per kilogram solvent. It is most commonly used in solving problems involving Colligative Properties (e.g. boiling point elevation, freezing point depression). Other ways to express concentration are Molarity, Mole Fraction, Parts per Million, Parts per Billion, and Normality.

Further Explanation

B. Mole Fraction is the ratio of the moles of a solute to the total moles of the solution. This unit of concentration is expressed as:

$mole\ fraction \ of \ x = \frac{moles \ of \ solute \ x}{total\ moles \ of \ solution}$

C. Molarity is the most common ways of expressing concentration. It is the amount of solute per liter of solution and is expressed as:

$Molarity\ (M) \ = \frac{moles \ of \ solute}{liter \ of \ solutiont}$

D. ppm (or parts per million) is used for very dilute solutions. It is expressed as the mass of solute in milligrams per liter of the solution:

$parts\ per \ million \ (ppm) = \frac{mass\ of \ solute \ (in\ mg)}{liter\ of\ solution}$

The first step in the two-step process of making a solution is the breakdown of the solute source into ____________."

Troyanec [42]

<h3><u>Answer;</u></h3>

Atomic particles

The first step in the two-step process of making a solution is the breakdown of the solute source into <u>atomic particles</u>.

<h3><u>Explanation</u>;</h3>

Solution is a homogeneous mixture of two or more substances uniformly dispersed throughout a single phase
<em><u>The liquid component that makes up the largest part of a solution is called the solvent, and the substance that is dissolved is called the solute.</u></em>
Unsaturated Solution is a solution that contains less solute than a saturated solution does and that is able to dissolve additional solute, while saturated Solution is a solution that cannot dissolve any more solute under the given conditions
