Answer:

Distance from earth

Explanation:

The star is classified based on following five basic properties:

1) brightness of star

2) color of star

3) surface temperature of star

4) size of star

5) mass of star

So based on this the only characteristics which is not used to classify stars is distance from earth as size, brightness, temperature are also related to age of stars.

What mass of sucrose needs to be dissolved in 540 g of water in order to prepare a 15% by mass solution.
Lilit [14]

Answer:

95.3g

Explanation:

Given parameters:

Mass of water  = 540g

Percentage by mass of solution = 15%

Unknown:

Mass of sucrose = ?

Solution;

To solve this problem, we must understand that a solution is made up of solute dissolved in a solvent. A solute is the solid dissolved in another. The solvent is the is dissolving medium;

    Percentage by mass of solute in solution = \frac{Mass of solute}{Mass of solution}  x 100

Mass of solution  = mass of water + Mass of sucrose  = 540 + M

  where M is the mass of sucrose;

therefore;

                 \frac{M}{540 + M }  x 100   = 15

   Solving for M gives 95.3g

Mass of sucrose is 95.3g
