What question do you need help with
Answer:
<h2>145 mL</h2>
Explanation:
The volume of the nugget can be found by using the formula
volume of object = final volume of water - initial volume of water
From the question
final volume of water = 225 mL
initial volume = 80 mL
We have
volume = 225 - 80 = 145 mL
We have the final answer as
<h3>145 mL</h3>
Hope this helps you
The correct answer is B. if im wrong please correct me if i am wrong
The empirical formula is C₂H₆O.
We must calculate the <em>masses of C, H, and O</em> from the masses given.
<em>Mass of C</em> =38.20 g CO₂ × (12.01 g C/44.01 g CO₂) = 10.424 g C
<em>Mass of H</em> = 23.48 g H₂O × (2.016 g H/18.02 g H₂O) = 2.6268 g H
<em>Mass of O</em> = Mass of compound - Mass of C - Mass of H
= (20.00 – 10.424 – 2.6268) g = 6.9487 g
Now, we must <em>convert these masses to moles</em> and <em>find their ratios</em>.
From here on, I like to summarize the calculations in a table.
<u>Element</u> <u>Mass/g</u> <u>Moles</u> <u>Ratio</u> <u>Integers</u>
C 10.424 0.8680 1.999 2
H 2.6268 2.606 6.001 6
O 6.9487 0.4343 1 1
The empirical formula is C₂H₆O.
