Answer:
Explanation:
To find the weight (W) of the pond contents first we need to use the following equation:
(1)
Where m the mass and g is the gravity
Also, we have that the mass is:
(2)
Where ρ is the density and V the volume
We cand calculate the volume as follows:
(3)
Where L is the length, w is the wide and d is the depth
By entering equation (2) and (3) into (1) we have:
Therefore, the weight of the pond is 6.65x10⁶ lbf.
I hope it helps you!

Explanation:
As it is given that both the given containers are at same temperature and pressure, therefore they have the same density.
So, mass of in container- 1 is as follows.
5.35 mol x molar mass of
= 7.61 mol x 146.06 g/mol
= 1111.52 g
Therefore, density of will be calculated as follows.
Density =
density =
= 0.532 g/mL
Now, mass of in container- 2 is calculated as follows.
4.46 L x 1000 mL/L x 0.532 g/mL
= 2372.72 g
Hence, calculate the moles of moles present in container 2 as follows.
No. of moles =
=
= 16.24 mol
Since, 1 mol contains 6 moles F atoms
.
So, 16.24 mol contains following number of atoms.
=
= 97.46 mol
Thus, we can conclude that moles of F atoms in container 2 are 97.46 mol.

Explanation:
The scientist mentioned above researched and made their tested hypothesis available for further research to be built on them and they do these researches to help human understanding of the field and therefore improve knowledge.
Through their different definitions of acid which includes the ability of hydrogen ion (H+) to be produced when a substance is separated from water, the ability of acid to donate a proton (H +), It can be concluded that acids contain hydrogen and they have the ability to donate that (H +) to other substance.
