Question

A solution contains 25 g of sugar in 225g of water. Calculate the concentration in terms of mass by mass percentage of the solution

Answer 1

solute- 25g
solvent- 225g
solution - 25+225=250 g
mass percentage of concentration=
25÷250 ×100 =
10 percent

Answer 2

Answer:

10%

Explanation:

Given:

solute mass = 25 g

and solvent mass = 225 g

To find:

Concentration

Solution:

The mass percentage of an element in a chemical or molecule represents the content, or percentage composition, of that particular element in that compound or molecule. It can be computed using the combined mass of the molecule and the mass of that particular element.

By dividing the mass of that substance by the overall mass of the combination, it is possible to determine an element's mass percentage composition. When calculating the mass percent of an element in a molecule, we divide the mass of the element's individual atom by the overall mass of the molecule.

So, mass of solution = mass of solvent + mass of solute.

250 g is the solution's mass (25 g + 225 g).

$mass\%=\frac{mass\hspace{0.1cm}of\hspace{0.1cm}solute}{mass\hspace{0.1cm}of\hspace{0.1cm}solution}\times100$

Substituting the value

mass % = $(\frac{25}{250} )\times100$

mass % = 10

A solution is prepared by adding 40 g of sugar in 100 g of water. Calculate the concentration in terms of mass by mass percentage of solution.
