Answer:
Explanation:
Hello,
In this case, for the given combustion process, we can compute the present moles of carbon atoms by considering that the only product containing carbon is CO2, thus, we have:
Next, we compute the moles of hydrogen that is present at the water only as a product:
Then, we compute the moles of oxygen by considering the oxygen present in both the CO2 and H2O and the initial sample:
Now, we divide the moles of C, H and O by the moles of O since they are lower amount, in order to compute the subscript in the empirical formula:
But the smallest whole number is:
Regards.
Answer:
160.3g
Explanation:
We know the equation:
No of moles = mass ÷ Mass of element
We need to find the mass, so make mass the subject of the formula.
Mass = No. of moles × mass of element
Mass = 5 × 32.06
Mass = 160.3g
The anticodons corresponding to the codons on the mRNA (from part A) is 5' CGA - AAA - GUU 3'.
<h3>What are anticodons?</h3>
Anticodons are nucleotide sequences on tRNA molecules that are complementary to the codons found on mRNA molecules.
The anticodons on tRNA molecules determine the amino acid that is carried by the tRNA.
Just like codons, anticodons occur in triplets of nucleotide sequences.
Considering the codons on the mRNA molecule:
3’ GCT | TTT | CAA | AAA ’5
The complementary anticodon will be:
5' CGA - AAA - GUU 3'

Answer:
173.5 g
Explanation:
This question seems incomplete, as the power by which 10 is increased is missing. I will answer this question assuming the given number of molecules is <em>7.03x10²³ </em>molecules. A different number of molecules will give a different answer, but the procedure remains the same.
First we <u>convert the given number of molecules into moles</u>, using <em>Avogadro's number</em>:
- 7.03x10²³ molecules ÷ 6.023x10²³ molecules/mol = 1.17 mol
Then we <u>convert magnesium nitrate moles into grams</u>, using its <em>molar mass</em>:
- 1.17 mol * 148.3 g/mol = 173.5 g
