Material of density of 762 kg/m3 occupies a container
konstantin123 [22]

Answer:

The answer is

<h2>0.075 kg</h2>

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

<h3>mass = Density × volume</h3>

From the question

density = 762 kg/m³

We must first convert the volume from cm³ to m³

1 \:  {cm}^{3}  = 1 \times  {10}^{ - 6}  {m}^{3}

So 99 cm³ will be

9.9 \times  {10 }^{ - 5}  \:  \:  {m}^{3}

So the mass of the material is

mass = 762 \times 9.9 \times  {10}^{ - 5}  \\  = 0.075438

We have the final answer as

<h3>0.075 kg</h3>

Hope this helps you

What is the pH of the solution in which the [H+] is 1.0 × 10–4 mol/L ?
ddd [48]
PH is a simplified observation of the acidity of a solution, defined as the -log [H+] (negative logarithm of the hydrogen concentration).

-log[10^-4] = 4

The pH of this solution is 4.

describe how knowledge of the periodic table would be important in three different careers, based on what you’ve read.
ANEK [815]

The knowledge of periodic table would be important in these three different careers such as medicine, pharmacology and engineering.

<h3>What is the importance of periodic table in following careers?</h3>

Periodic table is organised the whole elements vertically in groups and horizontally in periods with increasing atomic number.

The knowledge of arrangement of these elements serves alot of purposes in the following three different careers:

  • Medicine: The element, iron is an important metal in the periodic table used in treatment of low blood levels.

  • Pharmacology: The transition metals are useful in the field of pharmacology for the production of drugs. Example of such elements are chromium, manganese, cobalt, nickel, copper, and molybdenum.

  • Engineering: The information of elements in the periodic table helps engineers in designing of materials used for constructions.

Therefore, the knowledge of periodic table is very important in these three different careers such as medicine, pharmacology and engineering.

A saturated solution of potassium chlorate is dissolved in 100g of water. If the saturated solution is cooled from 90 degrees Ce
dedylja [7]

Mass would crystallize out : 24 g

<h3>Further explanation </h3>

Solubility is the maximum amount of a substance that can dissolve in some solvents. Factors that affect solubility

  • 1. Temperature:
  • 2. Surface area:
  • 3. Solvent type:
  • 4. Stirring process:

We can use solubility graph to solve this.

solubility KClO₃ at 90°C=52 g

solubilty KCl₃ at 60°C= 28 g

Mass would crystallize out = 52 - 28 =24 g
