Veseljchak [2.6K]
We can use the atomic model to demonstrate the ways in which scientists refine and build off each other's findings because of the fact that once this model was created, it brought with it other models and inventions, such as the periodic table and other theories about our known universe.

What is the percent-by-mass, %(m/m), concentration of sucrose ( table sugar) in a solution made by dissolving 22.8 g of sucrose
Ede4ka [16]

Answer:

32.6 %

Explanation:

Given data

  • Mass of sucrose (solute): 22.8 grams
  • Mass of water (solvent): 47.1 grams

Step 1: Calculate the mass of the solution

The mass of the solution is equal to the sum of the mass of the solute and the mass of the solvent.

m(solution) = m(solute) + m(solvent)

m(solution) = 22.8 g + 47.1 g

m(solution) = 69.9 g

Step 2: Calculate the percent-by-mass of sucrose in the solution

We will use the following expression.

\% m/m = \frac{mass\ of\ sucrose}{mass\ of\ solution} \times 100\% = \frac{22.8g}{69.9g} \times 100\% = 32.6 \%
