The solubility of co in water at 0c and 1 atm co pressure is 0. 0354 mg of co in 1 ml of water. Calculate the moalrity of aqueso

Dmitriy789 [7]

From all the calculations that were carried out, the concentration of 2atm is 0.0026 M.

<h3>What is molarity?</h3>

The term molarity is defined as the number of moles divided by the volume of the solution. Using the formula; C = kp where

C = concentration
k = constant
p = pressure

C = 0. 0354 * 10^-3 g/28 g/mol × 1000/1 L

C = 0.0013 M

k = C/p = 0.0013 M/1 atm

k = 0.0013 Matm-1

Now;

C = 0.0013 Matm-1 * 2 atm

C= 0.0026 M

6. How many moles are represented by 11.5 g of C2H5OH?

polet [3.4K]

Answer:

n C2H5OH = 0.2496 mol

Explanation:

moles (n) = mass / molecular weight

∴ m C2H5OH = 11.5 g

∴ Mw C2H5OH = (2)(12.011) + (6)(1.00794) + 15.9994 = 46.069 g/mol

⇒ n C2H5OH = (11.5 g)/(46.069 g/mol) = 0.2496 mol C2H5OH

In which tool are uranium atoms split to make electricity?

Anuta_ua [19.1K]

I'm assuming this refers to nuclear fission, which is in fact used to create heat, causing steam to spin turbines.
In which case, Uranium atoms are split by absorbing neutrons inside the reactor of a nuclear power station.

If you react 2.00 g of hydrogen completely using 15.87 g of oxygen to produce water, how much water (in grams) will you have?

leonid [27]

Answer:

The amount (mass) of water we will have is 17.869 grams

Explanation:

The molar mass of hydrogen gas H₂ = 2.016 grams/mole

The molar mass of oxygen gas = 31.999 g/mol

Therefore, 2.00 g of hydrogen will give;

2.00/2.016 = 0.9921 moles of H₂ gas and

15.87 g of O₂ will give;

15.87/31.999 = 0.49595 moles

The reaction is as follows;

2H₂ (g) + O₂ (g) → 2H₂O (l)

Two moles of H₂ react with one mole of O₂ to produce two moles of H₂O

Therefore 0.9921 moles of H₂ will react with 0.9921/2 or 0.49595 moles of O₂ to produce 0.9921 moles of H₂O

From the above we note that all the H₂ and O₂ are completely consumed to form 0.9921 moles of H₂O

Molar mass of H₂O = 18.01528 g/mol

Number of moles = Mass/(Molar mass)

∴ Mass of H₂O = (Molar mass) × (Number of moles)

= 18.01528 g/mol × 0.9921 moles = 17.869 grams

Therefore the amount (mass) of water we will have = 17.869 grams.

A bicycle tire has a volume of 1.0 l at 22°c. if the temperature of the tire is increased to 52°c, what is the resulting volume

tresset_1 [31]

The relationship between the volume, temperature, and pressure of the gas can be given by Charles law. The volume of the tire is 1.1 L.

<h3>What is Charle's law?</h3>

According to Charles's law, the volume is directly proportional to the temperature of the gas at a constant pressure.

Charle's law can be shown as,

$\rm \dfrac{V_{1}}{T_{1}} = \rm \dfrac{V_{2}}{T_{2}}$

Given,

Initial volume = 1.0 L

Initial temperature = 295 K

Final volume = ?

Final temperature = 325 K

Substituting values in the above equation the final volume can be calculated as:

$\begin{aligned}\rm V_{2} &= \rm \dfrac{V_{1}T_{2}}{T_{1}}\\\\&= \dfrac{ 1 \times 325}{295}\\\\&= 1.1\;\rm L\end{aligned}$

Therefore, the final resulting volume of the tire is 1.1 L.
