Answer:

10%

Explanation:

I think you are looking for mass percent concentration so...

concentration = (mass of solute / total mass of solution) x 100

concentration = (10g of NaCl / (10g of NaCl + 90g of H2O) solution) x 100

concentration = 0.1 x 100

concentration = 10%

Answer:

Concentration of solution is 0.1.

Explanation:

Given data:

Mass of NaCl = 10 g

Mass of water = 90 g

Concentration of solution = ?

Solution:

Formula:

Concentration = mass of solute / total mass of solution

Now we will calculate the total mass of solution:

Total mass of solution = mass of solute + mass of solvent

Total mass of solute = 10 g + 90 g

Total mass of solute = 100 g

Now we will determine the concentration,

C = 10 g/100 g

C = 0.1
