Question

In: Chemistry

Calculate the absolute uncertainty in the answer of the following: [(18.9±0.3)(1.89±0.05) - (1.07±0.02)(0.412±0.0009)] / [(4.79±0.06) +...

Calculate the absolute uncertainty in the answer of the following:

[(18.9±0.3)(1.89±0.05) - (1.07±0.02)(0.412±0.0009)] / [(4.79±0.06) + (1.37±0.02)]=

Please show how you got the answer.

Expert Solution

Answer:

This exercise on uncertainty , must be developed in 5 stages.

First stage: The specified product. (Let´s go Third stage).

Second stage: Other specified product. (Let´s go Third stage).

Third stage: The remains indicated in the numerator of the fraction (sum of first and second stages).

Fourth stage: The amount specified in the denominator of the fraction. (Let´s go fifth stage)

Fifth stage; The ratio between numerator (Let´s see third stage) and denominator (Let´s see forth stage) of the fraction referred develops.
