Calculate the number of moles of solute present and the number of grams

Chemistry
1 answer:
nekit [7.7K]3 years ago
6 0

Answer:

The answer is: 18 moles and 1341, 72 grams of KCl

Explanation:

The molarity is defined as the moles of solute ( in this case KCl) in 1 liter of solution:

1L solution-----3 moles of KCl

6L solution-----x= (6L solutionx 3 moles of KCl)/1 L solution= <em>18 moles of KCl</em>

<em></em>

We calculate the weight of 1 mol of KCl:

Weight 1 mol KCl= Weight K + Weight Cl= 39,09 g + 35, 45 g=74, 54 g/mol

1 mol KCl----- 74, 54 g

18 mol KCl----x= (18 mol KCl x 74, 54 g)/1 mol KCl=<em>1341, 72 g</em>

Read the following reactions.
garik1379 [7]

Answer:

Only Reaction 1

Explanation:

In reaction 1, there is a change in state from solid to liquid. Hence, there is an increase in number of ways particles and their energies could be arranged. As a result, entropy increases.

In reaction 2, there is a decrease in amount of gas particles (4 mol to 2 mol). Hence there is a decrease in the number of ways particles and their energies could be arranged. As a result entropy decreases

Sulfur dioxide gas (SO2) reacts with excess oxygen gas (O2) and excess liquid water (H2O) to form liquid sulfuric acid (H2SO4).
inessss [21]
A.2SO₂ + O₂ + 2H₂O → 2H₂SO₄
B.Moles of SO₂ = 67.2 / 22.4Moles of SO₂ = 3 molesMoles of H₂SO₄ = 3 molesMass of H₂SO₄ = 3 x 98Mass of H₂SO₄ = 294 grams
Assuming sulfuric acid to have the same density as water,density = 1000 g / LVolume = mass / densityVolume = 294 / 1000Volume = 0.29 liters of sulfuric acid

Number 1 do a data table on paper and do as it was said, then go into Microsoft Excel and put your chart in. For 2 make a line graph(as stated) and do what it tells you.For 3 do as said with the line graph or whatever it should look somewhat like a math chart(the coordinate plane) and do as said. For number 4 help him/her study the charts and analyze the difference between the two. And for number 5 make him/her choose one element and research and write down the questions.

A gas mixture contains ar and h2. what is the total pressure of the mixture, if the mole fraction of h2 is 0. 350 atm and the pr
nasty-shy [4]

Considering the Dalton's partial pressure, the total pressure in the mixture of gases is 1.371 atm.

The pressure exerted by a particular gas in a mixture is known as its partial pressure.

So, Dalton's law states that the total pressure of a gas mixture is equal to the sum of the pressures that each gas would exert if it were alone:

P_{T} = P_{1}+P_{2}+......+P_{n}

where n is the amount of gases in the mixture.

Dalton's partial pressure law can also be expressed in terms of the mole fraction of the gas in the mixture.  So in a mixture of two or more gases, the partial pressure of gas A can be expressed as:

P_{A} = X_{a}P_{T}

In this case, the partial pressure of gas H₂ can be expressed as:

P_{H2} = X_{H2} P_{T}

You know:

P_{H2} = 0.48 atm

X_{H2} = 0.35

Replacing in the definition of partial pressure of gas H₂:

0.48atm = 0.35P_{T}

Solving:

P_{T} = \frac{0.48atm}{0.35}

P_{T}= 1.371 atm

In summary, the total pressure in the mixture of gases is 1.371 atm.
