19) what is the molarity of a koh solution if 200 ml of the solution contains 0.6 moles koh?

3M

Explanation: Molarity : It is defined as the number of moles of solute present in one liter of solution.

Formula used :

where,

n = moles of solute = 0.6 moles

= volume of solution in ml= 200 ml

Now put all the given values in the formula of molarity, we get

Therefore, the molarity of solution will be 3M.

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.
