Question

What is the mass defect (in kg), if a isotope has an expected mass of 7.0586 amu and an actual mass of 7.0160 amu?

1 amu = 1.66 × 10-27 kg

0.0426 kg

14.1 kg

7.07 × 10-29 kg

2.34 × 10-26 kg

Answer 1

You would convert both masses to amu and then subtract to find the difference.

Answer 2

(Subtract the masses) and multiply by 1.7*10^-27kg
