<h2>
Answer: 8.93 g/cm³
</h2>
<h3>
Explanation:
</h3>
Density = mass ÷ volume
= 217.0 g ÷ 24.3 cm³
= 8.93 g/cm³
∴ the unknown sample of mass 217.0 grams and volume of 24.3 cm³ has a density of 8.93 g/cm³.
The question is asking to state the conclusion that can be formulated, base on the problem or the given analysis of the data, about the accuracy and precision and base on my research, i would say that the Accuracy is Poor but the Precision is Good. I hope this would help you
Frequency=speed over wavelength
so you need to know the value of speed in light inordet to figure out the frequency.
D is the correct answer for your question. Maybe I am not sure.
