The seawater of Puget Sound off the coast of Oregon has a salinity of about 24 PPT. What weight of salt is there in 1,000g of se
Juli2301 [7.4K]

The given salinity is 24ppt

The relation between salinity and grams is

salinity(ppt)=\frac{gramsofsolute}{massofsolventinkg}

it means there is 24 parts of salt per 1000 parts of water

ppt: parts per thousand

Or

there is 24 grams of salt per 1000g of water

thus the value 24 ppt signifies that there is 24g of salt dissolved in 1000g or 1kg of water

How does the attraction between particles affect the ability of a solvent to dissolve in a substance
Anni [7]

Explanation:

The attraction between solute particles affect its ability to dissolve in the solution because more is the attraction between particles less will be the chances that solute particles will combine to the solvent particles.

As a result, there will be decrease in solubility with increase in force of attraction between solute particles.

Whereas when there is less force of attraction between solute particles then more easily solute particles will combine with the solvent particles.

Hence, with decrease in force of attraction between solute particles, the rate of dissolution will increase.
