Calculate the volume in liters of a ×7.7310−5/mmolL silver(II) oxide solution that contains 475.μmol of silver(II) oxide AgO . R

Serhud [2]

Answer: Thus volume in liters is $6.14\times 10^3L$

Explanation:

Molarity is defined as the number of moles of solute dissolved per liter of the solution.

To calculate the number of moles for given molarity, we use the equation:

$\text{Molarity of the solution}=\frac{\text{Moles of silver oxide}}{\text{Volume of solution in L}}$ .....(1)

Molarity of silver oxide solution = $7.73\times 10^{-5}mmol/L=7.73\times 10^{-2}\mu mol/L$ $1mmol=1000\mu mol$

Moles of silver oxide = $475\mu mol$

Volume of solution in L = ?

Putting values in equation 1, we get:

$7.73\times 10^{-2}\mu mol\L=\frac{475\mu mol}{\text{Volume of solution in L}}\\\\\{\text{Volume of solution in L}}=\frac{475\mu mol}{7.73\times 10^{-2}\mu mol\L}=6.14\times 10^3L$

Thus volume in liters is $6.14\times 10^{3}L$

Reply ASAP: Why do electrons affect the structure of a molecule?

antoniya [11.8K]

Answer:

C. The electron clouds are negatively charged and repel each other as far apart as possible

Explanation:

This is the basis of VSEPR theory.

The angles between the electron clouds determine the shapes of the molecules.

B. and D. are wrong. All electron pairs are negatively charged.

The boundaries of a watershed are determined by

MrMuchimi

Answer: elevation , The boundaries of a watershed are determined by topography, which is the shape or the physical features of the land's surface. If the highest points of land surrounding a river were connected (like “connect-the-dots”), this line would form the watershed boundary.
