For any molecule, formula unit, or ion, the sum of the average atomic masses of all the atoms represented in a formula is the.
alukav5142 [94]

The mass of a substance is given in atomic mass units and is calculated by adding the average atomic masses of all the atoms in the substance's chemical formula.

<h3>What empirical formula represents the total average atomic mass of every atom?</h3>

The Method The average atomic masses of all the atoms included in a formula's representation are added to get the mass of any molecule, formula unit, or ion. It has no bearing on the number of significant figures because the number of atoms is an exact quantity. One H2O molecule weighs 18.02 amu on average.

<h3>What connection exists between the empirical formula and the molecular formula?</h3>

You can determine the number of atoms of each element in a molecule using its molecular formula. These empirical formulations provide the most basic or reduced elemental ratio of a compound. The empirical formula and the molecular formula of a substance are same if the molecular formula can no longer be decreased.

Where is pluto far from the sun or close<br> ?
AVprozaik [17]

Answer:

<u><em>Far</em></u>

But on average, Pluto is 3.7 billion miles (5.9 billion kilometers) away from the sun, or 39 AU. From 1979 to 1999, Pluto was near perihelion, when it is closest to the sun. During this time, Pluto was actually closer to the sun than Neptune.

It is moving farther and farther from the sun which is causing it to get colder and studies show it's atmosphere is disappearing as well.

Hope this helps :)

Once an electrical system has been installed and is considered to be an existing system, no safety-related design concepts can b
ludmilkaskok [199]

Answer:

False.

Explanation:

We can implement the safety related designs or devices to eliminate or mitigate after the installation of electrical system. For example we can install fuses in our homes or offices which detect if the current in the circuit exceeds it's limit. After the one fault fuse has to replaced with other one. There are many other electrical safety equipment that can be installed later on after the system installation.
