The table shows the mass in grams of one at of each of several elements. List the elements in order from least mass to greatest
kykrilka [37]

Answer:

Option B

Step-by-step explanation:

The question can be solved without observing the masses and calculating them.

How?

  • Periodic table law states that masses get increased in group and get decreased in period.
  • Hydrogen is the 1st element so it has least mass.

Now

Only option B and D has Hydrogen at first.

  • Rest omitted

Now coming to last elements Carbon and Gold

Gold is heavier as per periodic table.

So option B is correct

The radii of Earth and Pluto are 6,371 kilometers and 1,161 kilometers, respectively. Approximately how many spheres the size of
antoniya [11.8K]
The volume of a sphere is (4/3) (pi) (radius cubed).

The volume of one sphere divided by the volume of another one is

 (4/3) (pi) (radius-A)³ / (4/3) (pi) (radius-B)³

Divide top and bottom by (4/3) (pi) and you have     (radius-A)³ / (radius-B)³
and that's exactly the same as
                                                         ( radius-A / radius-B )  cubed.

I went through all of that to show you that the ratio of the volumes of two spheres
is the cube of the ratio of their radii.

Earth radius = 6,371 km
Pluto radius = 1,161 km

Ratio of their radii = (6,371 km) / (1,161 km)

Ratio of their volumes =  ( 6,371 / 1,161 ) cubed = about <u>165.2</u>

Note: 
I don't like the language of the question where it asks "How many spheres...".
This seems to be asking how many solid cue balls the size of Pluto could be
packed into a shell the size of the Earth, and that's not a simple solution.
The solution I have here is simply the ratio of volumes ... how many Plutos
can fit into a hollow Earth if the Plutos are melted and poured into the shell.
That's a different question, and a lot easier than dealing with solid cue balls.
