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:

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
