Calculate the density of an object with a mass of 6.147 and a volume of 9.3 (include units)
Olin [163]
Here is the formula for density:
Density (D) = Mass (M) divided by Volume (V)

So you would do D = 6.147 divided by 9.3

As an as answer you would get: 0.6609677419g/cm^3

Additional information:

The formula for volume is:
V = M divided by D


The formula for Mass is:
M = D times V


I hope this helps :)

How does the appearance of<br> the protist differ from that of the onion sample?
lana [24]

The appearance of the protist differ from that of the onion sample due to the presence of motile structures.

<h3>What is a Protist?</h3>

This is an eukaryote which could be unicellular or multicellular and examples include protozoa etc.

The major difference between a protist and onion sample is that protists have motile structures such as flagella, cilia etc while plant cells such as onions don't have.

Which is capable of housing while they conduct research
jeka94

Answer:

A space station

Explanation:

A space station provides an avenue for scientist to orbit the space and carryout scientific findings. Most space stations are usually controlled under agreement between different countries. The international space station is one such example.

A rover is usually a robotic device that has been pre-programmed and equipped with state of the art devices to carryout explorations on their own.

Most space observations are usually powerful telescopes on the earth surface that monitors events in space.

A satellite is a body that orbits another.

Which element would have the lowest electronegativity? (1 point)
lutik1710 [3]

The element which would have the lowest electronegativity is: an element with a small number of valence electrons and a large atomic radius.

Atomic radii can be defined as a measure of the size (distance) of the atom of a chemical element such as hydrogen, oxygen, carbon, nitrogen etc, typically from the nucleus to the valence electrons. The atomic radius of a chemical element decreases across the periodic table, typically from alkali metals (group one elements such as hydrogen, lithium and sodium) to noble gases (group eight elements such as argon, helium and neon). Also, the atomic radius of a chemical element increases down each group of the periodic table, typically from top to bottom (column).

Generally, atoms with relatively large atomic radii tend to have a low electronegativity, ionization energy and a low electron affinity.

Valence electrons can be defined as the number of electrons present in the outermost shell of an atom. Thus, number of valence electrons is typically used to determine the chemical properties of elements such as electronegativity.  

Electronegativity can be defined as the ability or tendency of the atom of an chemical element to attract any shared pair of electrons.

In conclusion, a chemical element that has small number of valence electrons and a large atomic radius would have the lowest electronegativity.
