An analyst reported 40.9 ppm Na in all 10 analyses of the standard solution having a true value of 40.11 ± 0.3 ppm. This data is:

Question

What will be the energy of 1 mole of photons having a wavelength of 200 nm?
Planck’s constant, \( h = 6.6 \times 10^{-34} \, \mathrm{Js} \) and Speed of light, \( c = 3.0 \times 10^8 \, \mathrm{ms^{-1}} \)

Answer 1

Precision: Consistent reporting of 40.9 ppm across 10 analyses demonstrates high precision and low variation.

Accuracy: The reported value of 40.9 ppm is accurate, falling within the true value's range of 40.11 ± 0.3 ppm.

Therefore, the data is both accurate (close to the true value) and precise (reproducible).
