Answer:

Given: Mass of salt (solute) = 25.0 g, Mass of solution = 80.0 g Required: % by mass salt solution Equation: % by mass = (mass of salt/mass of solution) x 100 Solution: % by mass = (25.0 g/80.0 g) x 100 % by mass = (0.3125) x 100 Answer: % by mass = 31.25% by mass salt solution This means that the presence of 25 g salt in an 80 g salt solution has a concentration of 31.25 % by mass.

Answer:

The cell is life's most fundamental unit and structure. Whether unicellular or multicellular creatures, all living things have cells. A living entity, such as yourself and other living things, is made up of cells, which are the simplest level of life. The metabolic activities that keep a living thing alive take place at the cellular level. The cell is known as the "fundamental unit of life" because of this.
