What pressure (in atm) is required to contain 0.034 moles of oxygen gas in a 5.1 L container at a temperature of 25.00C
kherson [118]

Answer:

0.16 atm

Explanation:

Let's look at the formula PV=nRT. First of all, T should be in kelvin, so let's add 273. Now solve for P so we get P = nRT/V.

Now let's plug these in...

P = (0.034 mol)(0.08206 L atm mol^-1 K^-1)(298 K)/5.1 L

After solving and rounding to sig figs we get 0.16 atm

Determine the molar mass of H2O2 (the solute) in a 1.5M aqueous solution of H2O2
Lera25 [3.4K]

Answer:

The molar mass of  H₂O₂ (the solute) in the aqueous solution of

H₂O₂ is 51 g

Explanation:

Given;

H₂O₂ compound

Concentration of aqueous solution of H₂O₂ = 1.5M

The molecular mass of H₂O₂ = (1 x 2) + (16 x 2) = 34 g/mol

Concentration(M) = \frac{Reacting \ mass \ (g)}{Molar \ mass \ (g/m)}

Reacting mass (g) = Concentration x Molar mass

Reacting mass (g) = 1.5 x 34

Reacting mass (g) = 51 g

Therefore, the molar mass of  H₂O₂ (the solute) in the aqueous solution of

H₂O₂ is 51 g

Do you expect the O---O bond in H2O2 to be longer or shorter than the O---O bond in O2?
melomori [17]

Answer : The O-O bond in H_2O_2 will be longer than the O-O bond in O_2.

Explanation :

In the H_2O_2, the two oxygen atoms are bonded by the single bond and in O_2, the two oxygen atoms are bonded by the double bond.

As we know, the bond strength of double bond is greater than the single bond.

And the relation between the bond strength and bond length is,

\text{ Bond strength}\propto \frac{1}{\text{ Bond length}}

That means the higher the strength, the shorter will be the bond length.

Hence, the bond length of single bond will be longer than the double bond.

The structure of given molecule is shown below.
