1L of bleach has a mass of 1,100 grams, 7.25% of the mass of bleach is NaClO, 1 mol of NaClO has a mass of 74.44 grams. What is the molarity (mol/L) of NaClO in the bleach? A.0.097 B.0.93 C. 1.07 D.79.75

C. 1.07 M.

Explanation:

Hello,

In this case, we can define the molarity of the bleach as shown below:

In such a way, given the mass of bleach in a 1-L solution, we can compute the density:

In such a way, we can use the previously computed density to compute the volume of the solution, assuming a 100-g solution given the by-mass percent:

Afterwards, using the by-mass percent of bleach we compute the mass:

And the moles:

Therefore, the molarity turns out:

Thus, answer is C. 1.07 M.

Regards.

if you mean hydrogen and oxygen then water is the product

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
