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:
A thick, dense fur, keeps the fox warm during winter, by preventing excessive loss of temperature and body heat when it is cold.
DNA, Deoxyribonucleic acid. DNA is the empirical proof of God.
DNA can never be created naturalistically and is absolutely uniquely structured:
1. DNA contains multiple levels of coded organically constructed information that controls all cellular functions and no natural process is capable of creating or coding.
2. The amino acids that provide the coding fo the genetic information are homochiral. The few, not all, amino acids that can form naturally are not symmetric and are either left-handed or right-handed, called racemic. All amino acids in DNA, RNA, proteins, enzymes, ribosomes and other cellular assemblies are left-handed, 100%. No right-handed amino acid can function within DNA. Nature may produce a partial list of racemic amino acids, but cannot produce homochiral amino acids, again, only produced within a cell.
3. Phosphate penta-sugars provide the overall dual backplane physical structure to allow the amino acids to be affixed and are all right-handed homochiral, not produced in nature and exclusively right-handed.
Answer: B
Explanation: Mars and Venus are terrestrial so a planet in between would be as well
Because wind is a source of energy which is non-polluting and renewable , is he turbines create power without using fossil fuels. Hope this helps!
