Perform the calculations and determine the absolute and percent relative uncertainty. Express each answer with the correct number of significant figures. a. [9.8(±0.3)−2.31(±0.01)]8.5(±0.6)=
b. absolute uncertainty:
c. absolute uncertainty:
d. percent relative uncertainty:

Explanation:

Given the equation:

The absolute uncertainty in a measurement is the term used to describe the degree of inaccuracy.

The first step is to determine the algebraic value on the numerator.

Algebraic value = 9.8 - 231

= 7.49

The absolute uncertainty =

absolute uncertainty =

=

= 0.300167

∴

[9.8(±0.3) - 2.31(±0.01)] = 7.49(±0.300167)

The division process now is:

Relative uncertainty =

Relative uncertainty = ±4.007565% ,  ±7.058824%

≅ 8%

The algebraic value =

= 0.881176

≅ 0.88

The percentage of the relative uncertainty =

By cross multiplying:

Finally:

c-14 is carbon-14, or radiocarbon.   it is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.
