Here is how the Mass Defect equation looks like.

0.8 = 2 \cdot 1.2 + (30 - 2) \cdot 1.3 - 38

0.8kg = 2 \cdot 1.2kg + (30 - 2) \cdot 1.3kg - 38kg

0.8 = 2 \cdot 1.2 + (30 - 2) \cdot 1.3 - 38

Mass Defect Solution

Follow our step by step solution on how to calculate Mass Defect?

FIRST Step Consider the formula

∆m = Z \cdot m p + (A - Z) \cdot m n - m atom

Next Step Substitute values of Variables

∴

∆m = 2 \cdot 1.2kg + (30 - 2) \cdot 1.3kg - 38kg

Next Step Prepare to Evaluate

∴

∆m = 2 \cdot 1.2 + (30 - 2) \cdot 1.3 - 38

Next Step Evaluate

∴

∆m = 0.799999999999997kg

LAST Step Rounding Answer

∴

∆m = 0.8kg
