Question

Molarity of NaOH: From the following data calculate molarity of NaOH. Molar mass of KHP is 204.23 g/mol. Show calculation. Mass of Erlenmeyer flask + KHP 84.847 g Mass of Erlenmeyer flask 84.347 g Mass of KHP ??? Final buret reading 12.25 mL Initial buret reading 0.50 mL Volume of NaOH added ???

Answer 1

Step-by-step explanation:

Mass of Erlenmeyer flask + KHP = 84.847 g

Mass of Erlenmeyer flask = 84.347 g

Mass of KHP = .5 g

moles of KHP = .5 / 204.23

= 2.448 x 10⁻³ moles

moles of NaOH reacted = 2.448 x 10⁻³

Final buret reading = 12.25 mL

Initial buret reading = 0.50 mL

Volume of NaOH added=
