Chemistry: You investigate the density of a chemical solution and get the results: 3.4 g/ml, 3.6 g/ml, and 3.7 g/ml. if the true density of the solution is 4.4 g/ml, what can be said about your results?

The results have poor accuracy but good precision. The results are not that close to the true solution so the accuracy is poor. The results are close to one another so the precision is good.

Chemistry

f = 17.14 cm

Explanation:

Given that,

The object distance, u = -40 cm

The image distance, v = +30 cm

We need to find the focal length of the lens. The lens formula is given by :

$\dfrac{1}{v}-\dfrac{1}{u}=\dfrac{1}{f}\\\\\dfrac{1}{f}=\dfrac{1}{30}-\dfrac{1}{(-40)}\\\\f=17.14\ cm$

So, the focal length of the lens is 17.14 cm.
