Answer:
Equation done below
Explanation:
Chlorine has two naturally occurring stable isotopes which are 35Cl (75.77%) and also 37Cl (24.23%).. However, the mass of the 35Cl isotope is 34.96885 amu while that of the 37Cl isotope is 36.96590 amu
Now, to calculate the relative atomic mass, we will do it as;
A_r = (Mass of 35Cl × fraction of 35 Cl) + (Mass of 37 Cl × fraction of 37Cl)
A_r = ((34.96885 × 75.77) + (36.96590 × 24.23))/100
A_r = 35.4527 ≈ 35.453 amu
This is a really hard question. Because if you change it to 1,000 then that's only one. If you add the decimal so it's 1,000. , then that's 4 if you change it to 1,040, that's 3. So you can not change that to 2 significant digits.
