Nucleic Acid is a complex organic substance present in living cells, especially DNA or RNA whose molecules consist of many nucleotides linked in a long chain.
Nucleotide is a compound consisting of a nucleoside linked to a phosphate group. They form the basic structural unit of nucleic acids such as DNA.
Answer:
M₁ = 0.178 M
Explanation:
In case of titration , the following formula can be used -
M₁V₁ = M₂V₂
where ,
M₁ = concentration of acid ,
V₁ = volume of acid,
M₂ = concentration of base ,
V₂ = volume of base,
from , the question ,
M₁ = ?
V₁ = 20.0 mL
M₂ = 0.158 M
V₂ = 22.60 mL
Using the above formula , the molarity of the acid , can be calculated as ,
M₁V₁ = M₂V₂
M₁ * 20.0 mL = 0.158 M * 22.60 mL
M₁ = 0.178 M
Answer:
its not c or d because we know nothing will happen to the bow- so its up to a and b- making the answer b :V
Explanation:
Answer: beta, gamma, alpha
Explanation: Beta is weakest gamma is middle alpha is strongest
Answer:
1.43 M
Explanation:
We'll begin by calculating the number of mole of the solid. This can be obtained as follow:
Mass of solid = 8.60 g
Molar mass of solid = 21.50 g/mol
Mole of solid =?
Mole = mass / molar mass
Mole of solid = 8.60 / 21.50
Mole of solid = 0.4 mole
Next, we shall convert 280 mL to litre (L). This can be obtained as follow:
1000 mL = 1 L
Therefore,
280 mL = 280 mL × 1 L / 1000 mL
280 mL = 0.28 L
Thus, 280 mL is equivalent to 0.28 L.
Finally, we shall determine the molarity of the solution. This can be obtained as illustrated below:
Mole of solid = 0.4 mole
Volume = 0.28 L
Molarity =?
Molarity = mole / Volume
Molarity = 0.4 / 0.28
Molarity = 1.43 M
Thus, the molarity of the solution is 1.43 M.
