Answer:
103.3 g
Explanation:
Data Given:
Volume of carbon tetrachloride (v) = 65.0 mL
Density of carbon tetrachloride (d) = 1.59 g/cm³
Solution:
Convert volume of carbon tetrachloride from ml to cm³
1 ml = 1 cm³
so,
65.0 mL = 65.0 cm³
Formula used to calculated mass of carbon tetrachloride should be taken for experiment.
d = m/v
Rearrange the above equation:
m = d x v . . . . . . .(1)
Put values in equation 1
m = 1.59 g/cm³ x 65.0 cm³
m = 103.3 g
The answer is A. Hope this helped
The three reasons that scientists found Rutherfor's nuclear atomic model to be fundamentally incomplete are as follows:
Number 1) according to Rutherford, the electrons revolve in completely
circular orbits. However, if this was true the charged electron would
simply fall into the nucleus after losing energy.
Number 2)
According to Rutherford's model, the nucleus itself only consisted of
protons. However, as we now know due to research in quantum mechanics,
if this was true this would make the atom unstable due to the cycle of
attraction and repulsion.
Number 3) The neutrons which have also
been discovered since to be an important part of the atom, are not
mentioned at all in Rutherford's model.
