Answer

Explanation:

Step1: Convert percentages to decimals

$17.30% = 0.1730$, $23.80%=0.2380$, $40.20% = 0.4020$, $18.70%=0.1870$

Step2: Calculate the contribution of each isotope

For Q - 101: $100.912\times0.1730 = 17.457776$ For Q - 102: $101.907\times0.2380=24.253866$ For Q - 103: $102.905\times0.4020 = 41.36781$ For Q - 104: $103.904\times0.1870=19.420048$

Step3: Sum up the contributions

$17.457776 + 24.253866+41.36781+19.420048 = 102.50$

Answer:

$102.50$
