First, set up a proportion:
You have 2.00 g Carbon and 7.33 g of the total substance (find it by adding 2.00g C + 5.33 g O)
You have an unknown g carbon with 55.0 g o total substance.
So:
Multiply 2.00 by 55.0 and divide the answer by 7.33
You'll get 20.63...
Since table salt is an ionic compound, the formula implies that numbers of Na+<span> ions, and Cl</span>-<span> ions are the same in the solid. The subscript numbers in an empirical formula should have no common divisor. A </span>structural<span> formula reflects the bonding of atoms in a molecule or ion.

Can you take a picture of the question and the experiment ? nobody can tell what experiment it is if you don’t show it
Answer:
Explanation:
Hello,
In this case, since in a dilution process the moles of the solute must remain unchanged, we use the volumes and molarities as shown below:
Clearly, the concentrated solution is 7.00M and the diluted solution is unknown, thus, the concentration of the diluted solution after the dilution to 100 mL is:
Best regards.
Answer:
- 7 g
Explanation:
Balancing of Nitrogen is a measure that deals with the difference between nitrogen intake and nitrgen loss
Nitrogen Balance = Nitrogen intake - Nitrogen loss
Given that
the nitrogen intake = 13 g and
the nitrogen loss= 21 g
Therefore nitrogen balance = nitrogen intake - nitrogen loss
= (13 - 21)g = -7 g
Thus, there is a negative nitrogen balance, meaning that the amount of nitrogen excreted from the body is greater than the amount of nitrogen ingested.
