Answer:

Density offers a convenient means of obtaining the mass of a body from its volume or vice versa; the mass is equal to the volume multiplied by the density (M = Vd), while the volume is equal to the mass divided by the density (V = M/d).

Explanation: Hope this helps :)

<u>Explanation:</u>

Unit is defined as the quantity that is used as a standard for measurement.

S.I. unit of mass of kilograms. Other units in which mass of a substance can be measured are grams, milligrams, etc...

All these units are inter convertible.

<u>For a:</u> Mega-

The conversion factor used is:

$1g=10^{-6}Mg$

<u>For b:</u> kilo-

The conversion factor used is:

$1g=10^{-3}kg$

<u>For c:</u> deci-

The conversion factor used is:

$1g=10dg$

<u>For d:</u> centi-

The conversion factor used is:

$1g=10^{3}cg$

<u>For e:</u> milli-

The conversion factor used is:

$1g=10^3mg$

<u>For f:</u> micro-

The conversion factor used is:

$1g=10^6\mu g$

<u>For g:</u> nano-

The conversion factor used is:

Given that the radius of the helium-4 nucleus is approximately 2.6 fm, the classical electron radius is 2.8 fm, and the calculat

Answer:

0.026%

Explanation:

The Helium-4 is the isotope of the helium that has a mass equal to 4. The element has 2 electrons, so, the total radius of the electrons is 2*2.8 = 5.6 fm = 0.0056 pm.

So, the total radius of the particles is 0.0056 + 0.0026 = 0.0082 pm.

The percentage of the space that the particles occupy is the radius of them divided by the radius of the atom:

% = 0.0082/31 *100%

% = 0.026%

* 1 fentometer (fm) = 0.001 picometer (pm)
