Question

There is an average of 3.5×10^−2 kilograms of dissolved salt in each liter of seawater. The South China Sea contains approximately ​ 9.88×10^18 ​ liters of seawater. How many kilograms of dissolved salt are in the South China Sea? Enter your answer, in scientific notation.

Answer 1

3.458×10^17 kilograms

Explanation:

3.5×10^−2 kilograms of dissolved salt in each liter of seawater.

The South China Sea contains approximately ​ 9.88×10^18 ​ liters of seawater.

Total salt in the sea = 3.5×10^−2 kilograms / liter * 9.88×10^18 ​ liters

= 3.458×10^17 kilograms

Answer 2

Hi There!

---------------------------------------------

We Know:

Dissolved Salt In Each Liter: 3.5 x 10^-2

South China Sea: 9.88 x 10^18

---------------------------------------------

Find:

How much dissolved salt is in the South China Sea.

---------------------------------------------

Solution:

Dissolved Salt: 3.5 x 10^-2 = 0.035 kg.

South China Sea: 9.88 x 10^18 = 9,880,000,000,000,000,000 kg.

Divide: (9.88 x 10^18) / 0.035 = 282,285,714,285,714,285,714.28571428571

Scientific Notation: 2.82285... x 10^17

---------------------------------------------

Answer:

2.82285... x 10^17
