Answer:
D
Explanation:
We have to bear in mind that the acid is a weak acid. A weak acid does not dissociate completely in solution. We will have more concentration of undissociated acid than A^- and H3O^+ and OH^- in the system at equilibrium.
Being a weak acid, there is maximum concentration of water molecules followed by that of undissiociated acid.
Hence, for this solution, the concentration of ions in solution follows the order;
[H2O] > [HA] > [A-] ~ [H3O ] > [OH-]
The answer is A.
We know the formula for molarity :
<u>Molarity = Number of moles ÷ Volume</u>

Let's assume there are 0.6 moles of NaCl in 1 liter of ocean water.
Then, mass of salt is :
- Mass of one mole salt × 0.6
- 58.5 × 0.6
- 35 grams
multiplying terrorist to power 23, divided by 96. Multiplied by 12.7. so this is 76.48
Buoyancy is considered a physical property. It is a type of physical property because it is related to the density and weight of the item, which are both physical.
