If the density of ocean water at a depth of 1.00 x 104 m is 1.071 g/mL and if 26.0 g of water at that depth contains 182mg of potassium chloride, what is the molarity of potassium chloride in the sample?

Molarity of potassium chloride is 0.100M

Explanation:

Molarity is defined as moles of solute per liter of solvent.

Moles of solute (Potassium chloride; MW: 74.55g/mol):

0.182g × (1mol / 74.55g) = 2.44x10⁻³mol KCl

Liters of water using density are:

26.0g Water × ( 1mL / 1.071g) × (1L / 1000mL) = 0.0243L

Thus, molarity of KCl in the sample is:

2.44x10⁻³mol KCl / 0.0243L = 0.100M

I hope it helps!

Explanation:

Below is an attachment containing the solution.

air quality

poor drinking water

and heavy polution

can lead to poor health

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.
