Answer:
a) 37.04% b) 37.04% c) 9.63%
Explanation:
The theoretical percent recovery (Tr), is the total percentage of each compound in the sample. Depending on the technique used to recovery the compounds, the percent recovery will be less than the theoretical, because no technique is 100% efficient.
So, to calculate the theoretical, it will be the mass of the compound divided by the mass of the sample multiplied by 100%.
a) Tr = (250 mg)/(675 mg) * 100%
Tr = 37.04%
b) Tr = (250 mg)/(675 mg) * 100%
Tr = 37.04%
c) Tr = (65 mg)/(675 mg) * 100%
Tr = 9.63%
It’s b. Shared between two atoms.
The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).
Protons and neutrons are in the center of the atom, making up the nucleus. Electrons surround the nucleus. Protons have a positive charge.
Each element has a specific mass number and a specific atomic number. These two numbers are fixed for an element. The mass number tells us the number (the sum of nucleons) of protons and neutrons in the nucleus of an atom. it has mass number 235 , it means that the sum of neutrons and protons in a carbon atom is 235.3
I took the mg and converted it to grams. That gave me .325 grams. I took that and multiplied that by 3628 grams. If I did my math correctly, the answer would be 1179.1. Rounded up, that would be 1179 aspirin tablets.
Hope this helps. :)
