39 years
Answer:
We conclude that:
Step-by-step explanation:
Given the expression
<u>Let us solve for 'c'</u>
Least Common Multiplier of 2n, 3c: 6nc
Now multiply both sides by LCM = 6nc
Simplify
Subtract 10n from both sides
Simplify
Subtract 6nc from both sides
Simplify
Factor 12c - 6nc = 6c(2-n)
Divide both sides by 6(2-n); n≠2
simplify
Therefore, we conclude that:
The atomic mass of an atom tells us about how much the atom weighs.
Option A
<u>Step-by-step explanation:</u>
The atomic mass of an atom tells us about the weight of the atoms. An atom can be represented using the mass number denoted as A and atomic number denoted by Z. As atomic number is the number of protons present in the atom, mass number denotes the sum of protons and neutrons present in the atom.
So, the mass number will be approximately equal to the atomic mass. It can be also stated that atomic mass represents the weight of the atoms. The elements are arranged in the increasing order of their atomic mass in the periodic table.
