Four haem groups and 4 globin
Answer : The mass of needed are, 44.5 grams.
Explanation :
First we have to calculate the moles of Na.
Now we have to calculate the moles of NaCl.
The balanced chemical reaction is:
From the reaction, we conclude that
As, 2 mole of produces from 2 mole of
So, 0.761 mole of produces from 0.761 mole of
Now we have to calculate the mass of
Molar mass of = 58.5 g/mole
Therefore, the mass of needed are, 44.5 grams.
Answer:
Excess nitrogen can harm water bodies
Answer:
79.90amu
Explanation:
To calculate the average atomic mass of an bromine we must multiply the masses of its isotopes with the percent abundance divided by 100. Then you add them together for your answer.
50.69 ÷ 100 = 0.5069
49.31 ÷ 100 = 0.4931
78.9183361amu × 0.5069 = 40.00amu
80.916289amu × 0.4931 = 39.90amu
40.00amu + 39.90amu = 79.90amu
Ar is classified as Argon in the periodic table it is a Noble gas having atomic number 18
