Answer:
47.871 amu
Explanation:
Average atomic mass of an atom is obtained from the sum of the mass of the isotopes multiplicated by its natural abundance.
That means atomic mass of Ti is:
Ti = 45.953*8.00% + 46.952*7.80% + 47.947*73.40% + 48.948*5.50% + 49.945*5.30%
Average atomic mass of Ti:
<h3>47.871 amu</h3>
The constents would be anythign that stays the same in ever experiment.
Example: Growing sunflowers in different liquids
The constants could be: Type of dirt used to grow each, amount of liquid used to water, and the type of sunflowers grown.
Answer:
A. To be precise, it must be able to make measurements repeatedly over a long period of time.
Explanation:
The precision of a scientific measuring tool can be defined as how close the values between multiple measurements are to each other, when repeated under the same conditions.
This ultimately implies that, the precision of a scientific measuring tool reflects the reproducibility and repeatability of its measurements, irrespective of how accurate the measurements are.
In science, one of the most effective ways to determine the precision of a scientific measuring tool is to find the difference between the highest and lowest measurements (measured values).
Hence, the statement which correctly describes a characteristic that a scientific measuring tool should have is that, to be precise, it must be able to make measurements repeatedly over a long period of time.
