Answer:

  • 2.31 × 10¹⁹ kg

Step-by-step explanation:

Each liter of seawater has 3.5 × 10⁻² kg of salt.

Number of liters of seawater is 6.6 × 10²⁰.

Total amount of salt is:

  • 3.5 × 10⁻² * 6.6 × 10²⁰ =
  • (3.5*6.6) × 10⁻²⁺²⁰ =
  • 23.1 × 10¹⁸ =
  • 2.31 × 10¹⁹ kg

3.5x10^(-2) kg/liter • 6.6x10^20 liters = 23.1 x 10^18 kg

But that's not back in scientific notation, because 23.1 is larger than 10.

   23.1 x 10^18 kg = 2.31 x 10^19 kg  

2.31 x 10^19 kg of salt
