Solution:

Given,

Weight of salt = 75 g

Quantity of water = 100 mL

As we know that, the formula of the percentage of the concentration is:

Concentration% = Mass of the solute / Mass of solute + Mass of solvent × 100

=> Concentration % = 75 / 175 × 100

=> Concentration % = 0.4285 × 100

=> Concentration % = 42.85 %

So, the concentration of the solute that is salt is 42.85%.

Now, for finding the concentration of solvent is:

Given,

Weight of salt = 75 g

Quantity of water = 100 mL

Concentration% = Mass of the solvent / Mass of solvent + Mass of solvent × 100

=> Concentration % = 100 / 175 × 100

=> Concentration % = 0.5714 × 100

=> Concentration % = 57.14 %

So, the concentration of the solvent that is water is 57.14%.

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.
