411.984 grams
The atomic mass of Silver is 107.8682 by the periodic chart I have here. That means that 1 mole of Silver masses
107.8682 grams if the Silver is pure.
I mole of any element like silver is also 6.022 X 10^23 atoms of silver.
10^24 atoms is therefore more than a mole. You specified
2.3 x 10^24 atoms, so the number of moles will be
(2.3 X 10^24)divided by 6.022 X 10^23 = 3.819 moles
this number X 107.8682 grams/mole gives us 411.984 grams
Answer:
90 Thymine bases
Explanation:
Chargaff's rules states that in the DNA of any organism, the amount of purine and pyrimidine bases must be in a 1:1 ratio. This means that the amount of Adenine and Guanine bases (purines) should be equal with their complementary pairs of Thymine and Cytosine bases respectively (pyrimidines). (A = T) + (G = C) = 100
Hence, according to this question, if there are 60 cytosine bases, this means that there will be 60 Guanine bases. 60 C + 60 G = 120 pyrimidines
300 total bases - 120 pyrimidine bases = 180 purine bases.
180/2 = 90 equal bases of Adenine and Thymine. Hence, Thymine bases will be 90.
- Due to the inability of the reaction to take place, the yield of 1-Bromobutane would drop.
- Since 1-Butanol won't react with the additional sodium bromide, bromination won't happen.
- If water had been supplied, the equilibrium would have shifted extremely far to the left, preventing the reactants from interacting with the acid and favoring the yield of 1-bromobutane instead.
<h3>What is Bromination?</h3>
- When a substance undergoes bromination, bromine is added to the compound as a result of the chemical reaction.
- After bromination, the result will have different properties from the initial reactant.
- For example, an alkene is brominated by electrophilic addition of
. - Benzene ring bromination by electrophilic aromatic substitution.
