Calculate the molar concentration of a solution containing 469 grams of C6H12O6 in 82 milliliters of water. The molar mass of C6
Maslowich

The molar concentration of a solution containing 469 grams of C6H12O6 in 82 milliliters of water is 31.7M.

<h3>HOW TO CALCULATE MOLAR CONCENTRATION:</h3>
  • The molar concentration of a solution can be calculated by dividing the number of moles by its volume.

  • According to this question, there are 469 grams of C6H12O6 in 82 milliliters of water.

The number of moles = 469g ÷ 180.156g/mol = 2.6mol

Volume of water in litres = 82/1000 = 0.082L

Concentration of solution = 2.6mol ÷ 0.082L = 31.71M

Therefore, the molar concentration of a solution containing 469 grams of C6H12O6 in 82 milliliters of water is 31.7M.

A 4.0 L balloon has a pressure of 406 kPa. When the pressure increases to 2,030 kPa, what is the volume? *
elena-14-01-66 [18.8K]

The new volume when pressure increases to 2,030 kPa is 0.8L

BOYLE'S LAW:

The new volume of a gas can be calculated using Boyle's law equation:

P1V1 = P2V2

Where;

  1. P1 = initial pressure (kPa)
  2. P2 = final pressure (kPa)
  3. V1 = initial volume (L)
  4. V2 = final volume (L)

According to this question, a 4.0 L balloon has a pressure of 406 kPa. When the pressure increases to 2,030 kPa, the volume is calculated as:

406 × 4 = 2030 × V2

1624 = 2030V2

V2 = 1624 ÷ 2030

V2 = 0.8L

Therefore, the new volume when pressure increases to 2,030 kPa is 0.8L.

What species is reduced in the reaction below?
lesya692 [45]

<u>Answer:</u> The correct option is D) Ag^+

<u>Explanation:</u>

The oxidation reaction is defined as the reaction in which a chemical species loses electrons in a chemical reaction. It occurs when oxidation number of a species increases.

A reduction reaction is defined as the reaction in which a chemical species gains electrons in a chemical reaction. It occurs when oxidation number of a species decreases.

For the given chemical reaction:

Zn^0+2Ag^+\rightarrow Zn^{2+}+2Ag^0

<u>On the reactant side:</u>

Oxidation number of Zn = 0

Oxidation number of Ag = +1

<u>On the product side:</u>

Oxidation number of Zn = +2

Oxidation number of Ag = 0

As the oxidation number of Ag is decreasing from +1 to 0. Thus, Ag^+ is getting reduced.

Hence, the correct option is D) Ag^+

Lena [83]
We calculate the entropy of an ideal gas follows:

<span>For an isothermal compression, change in internal energy is equal to zero.</span>
<span>Thus, the heat added to the gas is equal to the work done on the gas which is given as 1750 J.</span>

<span>Entropy would be 1750/301 = 5.81 J/K </span>
