It's the last answer. The gas-filled sacs allow for it to float, which means it's closer to the surface where the sun is. The top of the kelp collects the nutrients it needs from the sunlight and transfers it throughout the rest of it. Hope this helped!

Hello!</h2>
The answer is:
There are 732.24 grams of Dinitrogen Pentoxide in 6.78 moles of the same compound.
<h2>
Why?</h2>
The dinitrogen pentoxide, or nitrogen pentoxide, is a rare salt that consists of anion and cations, and it's an important compound when preparing some kinds of explosives.
So, to answer the question, first, need to look for the molecular formula of the dinitrogen pentoxide, then, use it to calculate the mass in gram of 6.78 moles of the same compound.
The dinitrogen pentoxide formula is:
Where, the molar mass of each element are:
Calculating the molar mass of the compound, we have:
Now, calculating what is the mass of 6.78 of , we have:
So, there are 732.24 grams of Dinitrogen Pentoxide in 6.78 moles of the same compound.
Have a nice day!
Answer:
OH⁻ = 1.05×10⁻¹³ M
Explanation:
Given data;
H₃O⁺ = 9.61×10⁻² M
OH⁻ = ?
Solution:
First of all we will calculate the pH.
pH = -log [H⁺]
pH = -log [H₃O⁺]
Because pH is also the hydronium ion concentration.
pH = -log [ 9.61×10⁻²]
pH = 1.02
It is known that,
pH + pOH = 14
1.02 + pOH = 14
pOH = 14 - 1.02
pOH = 12.98
Concentration of OH⁻.
pOH = -log [OH⁻]
12.98 = -log [OH⁻]
OH⁻ = 10∧-12.98
OH⁻ = 1.05×10⁻¹³ M
