Answer:
Mass number is defined as the number of protons plus the number of neutrons.
Explanation:
Every atom of an element have proton(s), neutron(s) and electron(s). The proton number of an element is the atomic number of that element. For an electronically neutral atom the proton number is equal to the electron numbers. The neutron and the proton contributes to the mass of every atom. The electron is more active when atoms are bonding.
Mass number of an element is the number of proton plus the number of neutron.
Atomic number of an atom is the number of proton present, so it can never be atomic number.
Isotopy talks about same element having different number of neutron but same number of protons in each atom. Example is hydrogen that exist as protium, deuterium and tritium. It cannot be isotopic number.
Ionic number talks about elements that possess a charge. The elements have been ionized.
The answer is Mass number because the sum of proton number and neutron number is equals to mass number.
FE is iron
iron is an element
so the answer is element 0-0
<span>179.35 mg of silver chloride is required to plate 135 mg of silver.
Create an expression showing what you know. Namely that 75.27% of X is equal to 135. So we get
75.27% X = 135
0.7527 X = 135
Now divide both sides by 0.7527
X = 135 mg / 0.7527 = 179.3543 mg
So it will take 179.35 mg of silver chloride to plate out 135 mg of pure silver.</span>
