He can conclude that his experiment has very low precision.

<h3>What is Precision ?</h3>

Precision is defined as the degree of refinement with which an operation is performed or a measurement .

Precision is how close the exact answers are together.

As, the answers are increasing in time.

None of the answers are similar to one another.

Hence, He can conclude that his experiment has very low precision.

How do you do these?
Agata [3.3K]

Solve these problems like weighted averages:

The first one:

Multiply the masses (isotope numbers) by the decimal form of the percentage. Add them

0.076 (6) + 0.924 (7) = 6.924


The second one:

0.2 (10) + 0.8 (11) = 10.8


If you think about it, these answers make sense. 6.924 is much closer to 7 than to 6 (since there's a lot more lithium-7 than there is lithium-6). 10.8 is closer to 11 than to 10.

A chemical formula for a molecular compound represents the composition of
Leni [432]

Answer:

A chemical formula for a molecular compound represents the composition of <u><em>a molecule.</em></u>

Explanation:

Chemical formulas are alphanumeric expressions that are used to indicate the composition of chemical substances. They consist of chemical symbols that indicate the elements that form a compound; The number of atoms provided by each element is also indicated by the use of a subscript, that is, a small number that is placed below and to the right of each element that so requires.  When an element does not have a subscript, it is understood that there is only one atom of it in the substance.

Each molecule corresponds to a chemical formula, as well as a name according to the rules of the chemical nomenclature.

Then, <u><em>a chemical formula for a molecular compound represents the composition of a molecule.</em></u>
