g If the titration of a 10.0-mL sample of sulfuric acid requires 28.15 mL of 0.100 M sodium hydroxide, what is the molarity of the acid

Explanation:

Hello,

In this case, the reaction between sulfuric acid and hydroxide is:

We can notice a 1:2 molar ratio between the acid and the base respectively, therefore, at the equivalence point we have:

And in terms of volumes and concentrations:

So we compute the molarity of sulfuric acid as shown below:

Best regards.

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
