The mass in grams of 8.94×10²² formula units of CuF₂ is 15.07 g
<h3>Avogadro's hypothesis </h3>
6.02×10²³ formula units = 1 mole of CuF₂
But
1 mole of CuF₂ = 101.5 g
Thus,
6.02×10²³ formula units = 101.5 g of CuF₂
<h3>How to determine the mass of 8.94×10²² formula units of CuF₂</h3>
6.02×10²³ formula units = 101.5 g of CuF₂
Therefore,
8.94×10²² formula units = (8.94×10²² × 101.5 ) / 6.02×10²³
8.94×10²² formula units = 15.07 g of CuF₂
Thus, 8.94×10²² formula units are present in 15.07 g of CuF₂

Compare it to the chart showing how base or acidic a substance is
Answer: The answer is A.
Explanation: The higher the kPa, the lower the boiling point
<u>The </u><u>scientific community </u><u>may act somewhat on restricted government </u><u>financing</u><u> circumstances throughout two ways:</u>
- Source for further money.
- Adjust this same scale and complexity of the investigation.
<u>Source for further money:</u>
- A researcher anyone who has restricted equipment and materials to finish an investigation might cooperate with certain other scientists as well as establish networking to exchange resources, thoughts, and behaviors for the survey's completion.
<u>Adjust this same scale and complexity of the investigation:</u>
- To decrease costs, the researchers might measure the study up by decreasing the levels initially intended for the investigation.
