Answer:
0.68L
Explanation:
First, let us calculate the number of mole in 100g of NaCl. This is illustrated below:
Molar Mass of NaCl = 23 + 35.5 = 58.5g/mol
Mass of NaCl = 100g
Number of mole of NaCl =?
Number of mole = Mass/Molar Mass
Number of mole of NaCl = 100/58.5
Number of mole of NaCl = 1.709 mole
Now we can find the volume of the solution as follow:
Mole = 1.709 mole
Molarity = 2.50M
Volume =?
Molarity = mole /Volume
Volume = mole /Molarity
Volume = 1.709/2.5
Volume = 0.68L
The mass and volume are thephysical properties that define matter. A matter is anything that can be seen or touched and is said to have mass, volume, density, and occupies space.
A matter is a substance present in the universe that occupies space and is said to have a definite volume and mass. Based on its physical arrangement and composition the matter can be gas, liquid, plasma, or solid.
The mass, volume, and density define the matter and its particles with specific mass and sizes due to the presence of sub-atomic particles like neutron, electron, and proton.
The amount of matter in the universe can be measured in kilograms and grams as mass, and the space occupied by it in cubic meters (m³) as volume.
Therefore, the matter is said to have volume and mass.

The amount of space between particles and their arrangement play a significant role in determining the state of matter—solid, liquid, or gas—and this relationship is closely linked to concepts of density, intermolecular forces, temperature, and pressure.
The relationship between the amount of space between particles and the state of matter is closely tied to the concepts of density and the arrangement of particles. The three primary states of matter are solid, liquid, and gas, and they exhibit different levels of particle spacing and arrangement:
Solid State: In a solid, particles are closely packed together in an ordered and fixed arrangement. The amount of space between particles is minimal, and they vibrate in place around fixed positions. Solids have a definite shape and volume due to the strong intermolecular forces that hold the particles together.
Liquid State: In a liquid, particles are still closely packed, but they have more freedom of movement compared to a solid. The intermolecular forces are weaker, allowing the particles to flow and move around one another. The amount of space between particles is larger than in a solid.
Gas State: In a gas, particles are widely spaced and move independently at high speeds. The amount of space between gas particles is much larger than in solids and liquids. Gases have neither a definite shape nor a definite volume, as they expand to fill the entire volume of their container.
This relationship between particle spacing and state of matter is described by the concept of density. Density is the mass of the substance per unit of the volume. Solids tend to have higher densities because their particles are densely packed, while liquids have lower densities due to the increased particle spacing.

Answer:
As the space changes between the particles, so does the state of matter. When the temperature of a solid is raised, the particles become more energetic, and they move farther and farther apart.

Answer:
The magnesium reacted with the oxygen in the air.
Explanation:
For argument’s sake, let’s say that the mass of magnesium oxide was 3 g and that of the oxide was 5 g.
The reaction was
magnesium + oxygen ⟶ magnesium oxide
Mass: 3 g 5 g
Mass of oxygen = 5 g – 3 g = 2 g
The 3 g of magnesium must have combined with 2 g of oxygen to form 5 g of magnesium oxide.
