Answer:

[H₂SO₄] = 6.07 M

Explanation:

Analyse the data given

8.01 m → 8.01 moles of solute in 1kg of solvent.

1.354 g/mL → Solution density

We convert the moles of solute to mass → 8.01 mol . 98g /1mol = 785.4 g

Mass of solvent = 1kg = 1000 g

Mass of solution = 1000g + 785.4 g = 1785.4 g

We apply density to determine the volume of solution

Density = Mass / volume → Volume = mass / density

1785.4 g / 1.354 g/mL = 1318.6 mL

We need this volume in L, in order to reach molarity:

1318.6 mL . 1L / 1000mL = 1.3186 L ≅ 1.32L

Molarity (mol/L) → 8.01 mol / 1.32L = 6.07M

Answer:6.08M

Explanation:

8.010 m means 8.010 mol / 1 kg of solvent

Molar mass of H2SO4=98g/mol

8.01mol × 98g/mol = 784.98 g of solute

784.98g + 1000 g = 1784.98g total for solute and solvent in the 8.010 m solution.

But density of acid=1.354g/ml

1784.98 g ÷ 1.354 g/mL = 1318.30 mL

1318.30/1000 = 1.3183L

8.01 moles / 1.3183 L = 6.08 M

6.08M

Rate how successful you were at using Active Reading skills by responding to the following statement: As i read, i paid attentio
Aleksandr-060686 [28]

It is possible to rate your active reading skills either by using a number is a specific rate or by using a word that qualifies your performance.

<h3>What are active reading skills?</h3>

Active reading skills are a set of skills that help you read actively; this means skills to effectively read a text and understand it.

<h3>How to rate your reading skills?</h3>

In this case, you are asked to rate your ability to pay attention to your understanding, thoughts, and questions while reading. To do this you can:

Rate using numbers:

  1. Select a specific scale rating such as 1 to 5 or 1 10.
  2. Analyze honestly if you used this ability while reading the text.
  3. Give yourself a number. For example, if you apply this skill only sometimes while reading you can rate yourself 5 out of 10.

Rate using words:

  1. Select the types of words that you will use, the most common ones are frequency words such as always, sometimes, and never.
  2. Analyze honestly your performance.
  3. Find the word that best fits it.

If the half-life of a radionulide is 1 month, what percent remains after 4 months?
Aliun [14]

Answer:

6.25% of the original amount

Explanation:

half-life means that half is gone for every certain period of time. Because the half life is 1 month, only half of the 'radionulide' is left every month.

after 1 month= 50%

after 2 months= 25%

after 3 months= 12.5%

after 4 months= 6.25%

When energy is added to a substance at constant volume and pressure, its temperature increases except ________.
Travka [436]

A. When the substance is in its gaseous state.

<u>Explanation:</u>

When a substance is expanding against its constant volume and pressure, its temperature increases except when the substance is in gaseous state and not in liquid or solid state. So the internal energy increase in the system not only increases and maintaining the volume and pressure of the system remains constant in its gaseous phase. In the first law of Thermodynamics, it is used specifically that to especially in the case of gaseous system.
