Question

40 g NaOH content in 400g H20.what it the percentage fraction of NaOh in this solution​

Answer 1

Ответ:

w(NaOH)= 40/400=0.1 (10%)

Answer 2

To calculate the percentage fraction of NaOH in the solution, you can use the following formula:

Percentage Fraction of NaOH = (Mass of NaOH / Total Mass of Solution) * 100

Given: Mass of NaOH = 40 g Total Mass of Solution = Mass of NaOH + Mass of H2O = 40 g + 400 g = 440 g

Now plug in the values:

Percentage Fraction of NaOH = (40 g / 440 g) * 100 ≈ 9.09%

So, the percentage fraction of NaOH in the solution is approximately 9.09%.
