QuestionCalculate the atomic mass of chlorine given isotopes: $91.51\%$ of ${ }^{35} \mathrm{Cl}$ ($34.97 \mathrm{amu}$) and $24.57\%$ of ${ }^{37} \mathrm{Cl}$ ($36.97 \mathrm{amu}$).

Studdy Solution
Calculate the atomic mass of chlorine.
$$Atomic\, mass = (0.9151 \\times34.97 \mathrm{amu}) + (0.2457 \\times36.97 \mathrm{amu})$$The atomic mass of chlorine is approximately $35.48 \mathrm{amu}$.
