Final Answer: The mass defect for a ₃₇Cl¹⁷ is 0.331160 amu.
Explanation: Given that,
The actual mass of ₃₇Cl¹⁷ = 36.966amu
no. of proton in ₃₇Cl¹⁷ = 17
no. of the neutron in ₃₇Cl¹⁷ = 20
mass of the proton = 1.00728
mass of neutron = 1.00867
We know that,
Defect mass = {(no. of proton × mass of proton) + (no. of neutrons × mass of neutron)} - actual mass
Δm = {(17 × 1.00728) + ( 20 × 1.00867)} - 36.966
Δm = (17.123760 + 20.173400) - 36.966
Δm = 37.297160 - 36.966
Δm = 0.331160 amu
