6 0

<u>Answer:</u> The concentration of solution is 0.342 M

<u>Explanation:</u>

To calculate the molarity of solution, we use the equation:

\text{Molarity of the solution}=\frac{\text{Mass of solute}\times 1000}{\text{Molar mass of solute}\times \text{Volume of solution (in mL)}}

We are given:

Mass of solute (Sodium chloride) = 15 g

Molar mass of sodium chloride = 58.5 g/mol

Volume of solution = 750 mL

Putting values in above equation, we get:

\text{Molarity of solution}=\frac{15g\times 1000}{58.5g/mol\times 750mL}\\\\\text{Molarity of solution}=0.342M

Hence, the concentration of solution is 0.342 M

Why do solids maintain a specific shape and volume?
s344n2d4d5 [400]

Answer:

Solids can hold their shape because their molecules are tightly packed together. ... Atoms and molecules in liquids and gases are bouncing and floating around, free to move where they want. The molecules in a solid are stuck in a specific structure or arrangement of atoms.

2. A cell with few energy needs would most
sattari [20]

A Cell with few energy needs would most likely contain a small number of Mitochondria.

  • All cells require energy to function, but cells typically have significant energy needs that can only be met by the mitochondria, the cell's powerhouse.
  • They transform glucose into ATP, a chemical with a huge energy storage capacity.
  • Muscles have a large number of mitochondria, allowing them to react rapidly and powerfully to the body's ongoing need for energy.
  • Macromolecules, defunct cell components, and microbes are all digested by lysosomes.
  • Vacuoles are typically tiny and aid in the sequestration of waste.
  • The ribosome, an intercellular structure consisting of both RNA and protein, is where a cell produces new proteins.

Therefore out of all these cell organelles, the cell has fewer mitochondria for less energy need.

Through what process do all stars produce their energy?
Deffense [45]

nuclear fusion

Stars produce their energy through nuclear fusion. For most stars, this process is dominated by a process called the "proton-proton chain," a sequence of events that transforms four hydrogen atoms into one helium atom.
