The final charge on each of the three separated spheres in part (b) is +3.0 μC. How many electrons would have to be added to one
marishachu [46]

Answer:

1.873\times 10^{13} electrons should be added to one of these spheres to make it electrically neutral.

Explanation:

Total charge on each sphere =  +3.0 μC =3\times 10^{-6} C

1 \mu C=10^{-6} C

In order to neutralize the positive charge equal magnitude of negative charge is to be added.

Total charge electrons, Q=  -3.0 μC =-3\times 10^{-6} C

Number of electrons = n

Charge on a single electron, e = -1.602\times 10^{-19} C

Q = n × e

-3\times 10^{-6} C=n\times (-1.602\times 10^{-19} C)

n=\frac{-3\times 10^{-6} C}{-1.602\times 10^{-19} C}=1.873\times 10^{13}

1.873\times 10^{13} electrons should be added to one of these spheres to make it electrically neutral.

A concentrated salt solution has a mass of 5.222 g for a 5.000 mL sample.
ad-work [718]

The specific gravity or relative density of a substance is the ratio of its density to the density of a reference material. The relative density of the concentrated salt solution is 1.044.

Mathematically;

Density of the concentrated salt = mass of salt/volume of salt = 5.222 g/5.000 mL = 1.044 g/mL

In the case of specific gravity, the reference material is always water and water has a density of 1 g/mL.

Hence, specific gravity of the concentrated salt solution =

Density of concentrated salt solution/density of equal volume of water

= 1.044 g/mL/1 g/mL

= 1.044

Note that specific gravity is dimensionless.
