How many grams of pure naoh must be used to prepare 10.0 l of a solution that has a ph of 13? ?

We must use 39.997 grams of NaOH to prepare 10.0 L of a solution that has a pH of 13.

To find the mass of NaOH, we need to calculate the number of moles.  

From the pH, we have:

The pOH is given by

Now, we can find the number of moles with the volume of solution

Finally, we can calculate the mass

Therefore, we need to use 39.997 g of NaOH.

40 g NaOH. You must use 40 g NaOH to prepare 10.0 L of a solution that has a pH of 13.

Step 1. Calculate the pOH of the solution

pOH = 14.00 – pH = 14.00 -13 = 1

Step 2. Calculate the concentration of NaOH

[NaOH] = [OH^(-)] = 10^(-pOH) mol/L = 10^(-1) mol/L = 0.1 mol/L

Step 3. Calculate the moles of NaOH

Moles of NaOH = 10.0 L solution × (0.1 mol NaOH/1 L solution) = 1 mol NaOH

Step 4. Calculate the mass of NaOH

Mass of NaOH = 1 mol NaOH × (40.00 g NaOH/1 mol NaOH) = 40 g NaOH

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.
