Question

A saline solution with a mass of 355 g has 36.5 g of NaCl dissolved in it. What is the mass/mass

percent concentration of the solution?​

Answer 1

Answer:

10.28%

Explanation:

mass of saline solution=355gram

mass of sodium chloride (solute)=36.5gram.

mass by mass = mass of solute/

percentage of the. = mass of solution

solution=. *100

therefore,. (36.5/355)100

=10.28%

Answer 2

A saline solution with a mass of 355 g has 36.5 g of NaCl dissolved in it.

we have to find the mass/mass percent concentration of the solution.

mass/mass percent concentration :

it is just a way of expressing the concentration of solution. it is expressed as the mass of solute in gram divided by mass of the solution in gram and then multiplied by 100.

in short, w/W % = mass of solute/mass of solution × 100

here the mass of NaCl ( solute) = 36.5 g

mass of the solution = 355 g

now the mass/mass percent = $\frac{36.5g}{355g}\times100$  = 10.28 %

Therefore the mass/mass percent concentration of the solution is 10.28 %.
