Calculate the density, in g / mL , of a liquid that has a mass of 0.125 g and a volume of 0.000285 L

Chemistry
1 answer:
maria [59]3 years ago

Answer:

ρ = 0.439 g/mL

Explanation:

Given data

  • Mass of the liquid: 0.125 grams
  • Volume of the liquid: 0.285 milliliters

0.000285 L × (1000 mL/ 1 L) = 0.285 mL

The density (ρ) of a liquid is equal to its mass (m) divided by its volume (V).

ρ = m/V

ρ = 0.125 g/0.285 mL

ρ = 0.439 g/mL

The density of the liquid is 0.439 g/mL.

The atomic number,atomic mass,valence electrons and the formula for calculating the number of neutrons is also given.The following table has been completed below in the attachment.

Explanation:

Atomic Number:the number of protons /electrons present in the nucleus of an atom is called the atomic number.

Mass Number/Atomic Mass:the number of protons and neutrons present in a nucleus

<u>Example:</u>C_{6} ^{12};here;6 implies the atomic number and 12 implies the mass number/atomic mass

<u><em>No.of neutrons=Mass number-Number of protons</em></u>

Valence electrons:the number of electrons present in the outer most shell of an atom are called valence electrons

<u>Example:</u>If we consider a carbon atom;as its <em>e</em><em>lectronic configuration is2,4 and</em>  it belongs to 4th group.Therefore the number of valency electrons in carbon is <u>4.</u>

Newton's second law of motion uses the formula which states that a force will cause a mass to accelerate. (f = m •
Makovka662 [10]

Newton's second law of motion can be formally stated as follows:

The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

This verbal statement can be expressed in equation form as follows:

a = Fnet / m

Consider the following balanced equation:
algol [13]

Moles of PF₃ : 4

<h3>Further explanation</h3>

A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.

Reaction

\tt P_4(s)+6F_2(g)\rightarrow 4PF_3(g)

1.25 moles of P₄(s) is reacted with 6 moles of F₂(g)

Limiting reactant : the smallest ratio (mol divide by coefficient)

P₄ : F₂ =

\tt \dfrac{1.25}{1}\div \dfrac{6}{6}=1.25\div 1\rightarrow F_2~limiting~reactant(smallest~ratio)

mol PF₃ based on mol of limiting reactant(F₂), so mol PF₃ :

\tt \dfrac{4}{6}\times 6~moles=4~moles
