To make a saturated solution, 36 gm of sodium chloride is dissolved in 100 gm of water at 293 K. Find its concentration at this temperature.

Mass per cent is a way of expressing a concentration or describing the component in a particular mixture. The solution composition can be expressed in mass percentage that depicts the mass of solute present in a given mass of solution.

The quantity of solute is expressed in mass or by moles. For a solution, the mass per cent is described as the grams of solute per grams of solution, multiplied by 100 to get the percentage.

Concentration

Mass of sodium chloride (Solute) = 36gm

Mass of water (solvent) = 100 gm

Mass of solution = 36+100

∴ Mass of solution = 136 gm

Concentration = (Mass of Solute / Mass of Solution) * 100

Concentration = (36/136) × 100

Concentration = 26.47%

Temperature

If temperature increases, solubility increases and if temperature decreases, solubility decreases.

It is possible to distinguish the particles of solute from those of solvent in a suspension, since particle size is bigger in suspensions, hence it is easier to distinguish the particles of solute.

Explanation:

elements make up everything, and they combine to make compounds.

the answer is c

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
