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.

relative humidity is a measure of the amount of moisture in the air relative to the total amount of moisture the air can hold.

so d

answer: option (4) is the correct answer.

explanation:

areas which are at low altitudes and near the equator tend to receive direct sunlight from the sun. hence, heat energy or radiations from the sun make these areas warmer and they have warmest water.

whereas areas which are at high altitudes and away from the equator do no receive direct sunlight. hence, no direct contact from the sun makes these regions colder and thus, they have colder water.

thus, we can conclude that the statement areas at low latitudes near the equator have the warmest water because they receive the most direct sunlight best explains the relationship between an area's geography and the temperature of its surface water.
