Answer: -

True

Explanation: -

The equivalence point in a titration is the point when both the acid and base have been completely consumed.

Total amount of acid present = [H⁺ ]

Total amount of base present = [OH⁻ ]

Thus at equivalence point,

total amount of base should be equal to total amount of acid.

[H⁺] = [OH⁻]

First we need to find the number of moles of both K and O reacted
K - 0.779 g / 39 g/mol
= 0.02 mol
the mass of O₂ reacted = 1.417 g - 0.779 g = 0.638 g
O₂ moles = 0.638 g / 32 g/mol
= 0.02 mol
the number of both K and O₂ moles reacted are equal
therefore stoichiometry of K to O₂ reacted are 1:1
then the formula of potassium superoxide is KO₂

How is the precision of a calculated result related to the precision of the measurement used in the calculation?

sashaice [31]

The precision of a calculated answer is limited by the least precise measurements used in the calculation.

Hope this helps :)
