The answer is 43.72 <span>× 10¹² kg.</span>
It is given:
the mass of the Rock of Gibraltar:
m₁ = 1.78 × 10¹² kg
the mass of the Antarctic iceberg:<span>
m</span>₂ = 4.55 × 10¹³ kg = 4.55 × 10 × 10¹² kg = 45.5 × 10¹² kg<span>
To calculate how many more kilograms </span><span>is the mass of the Antarctic iceberg than the mass of the Rock of Gibraltar we need to subtract them:
</span>m₂ - m₁ = 45.5 × 10¹² kg - <span>1.78 × 10¹² kg
</span>m₂ - m₁ = (45.5 - 1.78) <span>× 10¹² kg
</span>m₂ - m₁ = 43.72 × 10¹² kg
