2. a volume is measured experimentally as 4.26 ml. what is the percentage error, given that
the correct value is 4.15 ml?
measurements and calculation

0.73% error

Explanation:

Take the absolute value of the measured value minus the actual value and divive it by the actual value. Then multiply it by 100%.

I 4.26-4.15 I = 0.11/4.15 = 0.007333 x100% = 0.73%

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
