Answer:
Two
Step-by-step explanation:
In <em>multiplication problems</em>, your answer can have no more significant figures than the number with the <em>fewest significant figures</em>.
Start with the calculation inside parentheses:
5.1 × 10.6 = 54.060 000 00 (by my calculator)
There are three significant figures in 10.6, but only two in 5.1.
In this were a number you had to report, you would round to <em>two</em> significant figures and report the answer as 54.
54.060 000 00 → 54 (to two significant figures)
However, you must multiply this intermediate answer by 2.524.
Therefore, you multiply the number in the calculator by 2.524 and get
54.060 000 00 × 2.524 = 136.447 4400
<em>NOW</em>, you round to two significant figures and report the answer as <em>140</em>.

Explanation:
I'm not sure if this is what you are looking for but i will attempt to answer.
Isotopes are variations of the same atom. They have the same number of protons but have a different number of neutrons. As a result of this, the atomic number remains the same but the mass number changes.
A calculation you could perform in relation to isotopes would be calculating the relative atomic mass. The relative atomic mass is the weighted average of masses of isotopes.
Relative atomic mass (RAM)= the addition of
For example, the element Indium has a relative isotopic mass of 112.90406, 4.29% of the time. It has a relative isotopic mass of 114.903878, 95.71% of the time.
From this
RAM=
