Answer:
The atomic mass of Zinc is 65.30 Da
Explanation:
<u>Step 1: </u>Data given
3 major isotopes
⇒ Zinc-64
atomic mass = 63.929 Da
Peak intensity = 100
⇒ Zinc-66
atomic mass = 65.9260 Da
Peak intensity = 57.4
⇒ Zinc- 68
atomic mass = 67.9248 Da
Peak intensity = 38.6
<u />
<u>Step 2:</u> Calculate the natural abundance
∑peak intensity = 100 + 57.4 + 38.6 = 196
Zinc-64 : 100/196 = 0.5102 ⇒ 51.02 %
Zinc-66 : 57.4/196 = 0.2929 ⇒ 29.29 %
Zinc-68 : 38.6/196 = 0.1969 ⇒ 19.69 %
<u>Step 3:</u> Calculate the atomic mass if Zinc
63.9291 * 0.5102 + 65.9260*0.2929 + 67.9248*0.1969 = 65.3007 Da
The atomic mass of Zinc is 65.30 Da
