Ask your teacher sodium hydroxide solution is usually standardized by titrating a pure sample of potassium hydrogen phthalate (khc8h4o4, often abbreviated khp), an acid with one acidic hydrogen and a molar mass of 204.220 g/mol. it takes 36.01 ml of a sodium hydroxide solution to titrate a 0.1182-g sample of khp. what is the molarity of the sodium hydroxide

0.0161 M

Explanation:

Moles of KHP :

Given, Mass of KHP = 0.1182 g  

Molar mass of KHP = 204.22 g/mol

The formula for the calculation of moles is shown below:

Thus,

According to the reaction shown below:

KHP + NaOH ⇒ KNaP + H₂O

1 mole of KHP reacts with 1 mole of NaOH

So,

of KHP reacts with of NaOH

Moles of NaOH =

Volume = 36.01 mL = 0.03601 L ( 1 mL = 0.001 L)

nuclear fission produces elements that are heavier than helium.

the elements that are used in nuclear fission and their products are much heavier than helium.
