Answer:
30grams
Explanation:
To calculate the mass (number of grams of the solute) in the solution, we need to calculate the number of moles it contains first. We use the formula;
M = n÷ V
Where; M= Molarity or Molar concentration = 2.055M
n= number of moles= ?
V= Volume = 250mL
Volume in L is 250/1000 = 0.250L
n= M × V
n= 2.055 × 0.250
n= 0.51375moles
The mass is calculated using :
Mole (n) = mass (m) / molar mass (MM)
Molar mass of NaCl = 23 + 35.5
= 58.5g/mol
Mass = molar mass × mole
Mass = 58.5 × 0.51375
Mass = 30.0543
Therefore, the mass is 30grams
Answer:
This way, for 20^2.55 = 2109 amino acids are require to have 2*1056 number different sequences.
Explanation:
Protein should contain 2*1056 of different sequence so
2*1056 = 20^x
Log (2*1056) = log 20^x
3.3246 = (x ) * 1.3010
X= 2.555
Celular respiration is:
Oxygen + glucose --> carbon dioxide + water
Carbon dioxide and water are both compounds, which makes them both molecules.
They're both byproducts of cellular respiration.

Hmmm i think its the third one because men only have 1 x chromosome therefore without the other one if the x chromosome on a men carries a disorder it will show because there is no other chromosome to balance it out and in women the disorder has to show on both X chronosome (and its rarer) for a disorder to appear therefore women having a second X chromosome is effectively a protection
