Solution

The correct option is C 1.96 %Given: mass of substance = 0.5 g Mass of solvent = 25 g %ww=weight of the component in solution (g)total weight of the solution (g)×100 %ww=0.50.5+25×100=1.96%

Solution : Mass of solute (common salt) = 0.5 g <br> Mass of solvent (water) = 25 g <br> Mass of solution = (0.5 + 25)g = 25.5 g <br> Now, Mass percentage of solution <br> = `("Mass of solute")/("Mass of solution")xx100` <br> = `0.5/25.5xx100` <br> = 1.96%

Given, Mass of salt present = 0.5 g
Mass of water present in solution = 25 g

Mass of solution = Mass of salt + Mass of solvent =0.5 + 25= 25.5 g
{tex}\therefore{/tex} Percentage amount of the salt in solution={tex}\frac{Mass\;of\;salt}{Mass\;of\;solution}\times100{/tex}= {tex}\frac{0.5}{25.5} \times 100=1.96 \%{/tex}

Classification and Properties of Matter

In chemistry and physics, matter is any substance that has mass and takes up space by having volume. All everyday objects that can be touched are ultimately composed of atoms, which are made up of interacting subatomic particles, and in everyday as well as scientific usage, "matter" generally includes atoms and anything made up of them, and any particles and objects that act as if they have both rest mass and volume. However it does not include massless particles such as photons, or other energy phenomena or waves such as light or sound. Matter exists in various states (known as phases) that are defined by various physical properties, such as state of matter, phase, shape, and density. The Standard Model of particle physics and the general theory of relativity describe fundamental particles and the fundamental forces acting between them that control the structure and dynamics of matter.
