Question

В 150 граммах 20% раствора серной кислоты содержится кислота какой массы?

Answer 1

150=100%
Х гр=20%
Х=150*20/100=60 граммов серной кислоты

Answer 2

Calculating the Mass of Sulfuric Acid in 150 Grams of 20% Solution

To calculate the mass of sulfuric acid in a 150-gram solution of 20% sulfuric acid, we can use the formula:

Mass = Volume × Concentration

In this case, the volume is not given, but we can assume it to be 150 grams for the purpose of this calculation. The concentration is 20%.

Using the given information, we can calculate the mass of sulfuric acid in the solution.

Mass of Sulfuric Acid = Volume of Solution × Concentration of Sulfuric Acid

Mass of Sulfuric Acid = 150 grams × 20%

Mass of Sulfuric Acid = 150 grams × 0.20

Mass of Sulfuric Acid = 30 grams

So, in a 150-gram solution of 20% sulfuric acid, the mass of sulfuric acid is 30 grams.
