True, to convert from moles to atoms, multiply the molar amount by Avogadro's number. To convert from atoms to moles, divide the atom amount by Avogadro's number (or multiply by its reciprocal).

Answer:
220.42098 amu
Explanation:
(220 .9 X .7422) + (220 X .0.1278) + (218.1 X 0.13) = 220.42098 amu
These are weighted averages.
So, we will take mass of one and multiply by abundance percentage that is provided and add them together.
In order to calculate the average atomic mass, we have to convert the percentages of abundance to decimals. So, you get
(220 .9 X .7422) + (220 X .0.1278) + (218.1 X 0.13) = 220.42098 amu
Answer:
The degree of unsaturation for a compound with molecular formula C₆H₆ is 4.
Explanation:
The degree of unsaturation is calculated through the following formula:
2n + 2 - H / 2
n = Total number of hydrogen in given compound
There are six hydrogen in given compound, now we will calculate the degree of unsaturation by putting the value of n= 6
(2(6) + 2 - 6 )/ 2
(12+ 2 - 6) / 2
(14 - 6) /2
8 / 2 = 4
The degree of unsaturation for a compound with molecular formula C₆H₆ is 4.
The given compound is benzene and degree of unsaturation is 4. Three double bond and one ring.
I think the answer is D add a base like limestone or calcium carbonate. Hope this helps and pls correct me if im right or wrong, i would appreciate that :)
