Question

Расчитайте массу соли которая растворены в водах Азовского моря если средняя соленость его вод составляет 12% объем 256 км3

Answer 1

&=m/V*100%
m=&V/100%
m=0.12*256=30.72

Answer 2

Calculation of the Mass of Salt in the Azov Sea

To calculate the mass of salt dissolved in the waters of the Azov Sea, we need to know the average salinity of its water and the volume of the sea.

According to the information provided, the average salinity of the Azov Sea is 12% by volume, and the volume is 256 km³.

To calculate the mass of salt, we can use the formula:

Mass of Salt = Volume of Water x Salinity

Substituting the given values:

Mass of Salt = 256 km³ x 12%

Now, let's calculate the mass of salt:

Mass of Salt = 256 km³ x 0.12

To convert the volume from km³ to m³, we need to multiply by 1,000,000,000 (1 km³ = 1,000,000,000 m³):

Mass of Salt = 256,000,000,000 m³ x 0.12

Calculating the result:

Mass of Salt = 30,720,000,000 m³

Therefore, the mass of salt dissolved in the waters of the Azov Sea is approximately 30,720,000,000 metric tons.

Please note that the calculation assumes a uniform distribution of salinity throughout the entire volume of the sea.
