A chemist needs to determine the concentration of a sulfuric acid solution by titration with a standard sodium hydroxide solutio
brilliants [131]

Explanation:

The given data is as follows.

          Concentration of standard NaOH solution = 0.1922 M

Let the original acid solution concentration be x.

                        M_{1}V_{1} = M_{2}V_{2}

                        x \times 25 = 250 \times M_{2}

                         M_{2} = \frac{x \times 25}{250}

                                     = 0.1 x M

V_{2} = 10.00 mL (given)

The reaction equation is as follows.

             2NaOH + H_{2}SO_{4} \rightarrow Na_{2}SO_{4} + 2H_{2}O

   Concentration × Volume of H_{2}SO_{4} = Concentration × Volume of NaOH

           \frac{M_{2}V_{2}}{n_{2}} = \frac{M_{3}V_{3}}{n_{3}}

     \frac{0.1 x \times 10 ml}{1} = \frac{0.1922 M \times 13.68 ml}{2}

                  x = 1.314 M

Therefore, we can conclude that the concentration of the original sulfuric acid solution is 1.314 M.

At 3pm a dry-bulb thermometer reading is 66F the wet-bulb reading is 66F what is the relative humidity explain? Plzzzz help <
BARSIC [14]

Answer:

100 %

Explanation:

<em>Relative humidity</em> (RH) is the amount of water vapour in the air compared to the maximum amount it can hold, expressed as a percentage.

RH is measured by a device that has wet- and dry-bulb thermometers.

If the air is unsaturated, water will evaporate from the wet bulb and cool it. The wet-bulb temperature will be less than that of the dry bulb.

If the wet-bulb temperature is the same as the dry-bulb temperature, it means that water cannot evaporate from the wet bulb.

The atmosphere already holds as much water as it possibly can, so the relative humidity is 100 %.
