Calculating mass of a substance
From the question, we are to calculate the mass of salt in 70 liters.
From the given information,
The salt content in the Caspian Sea is 0.13 kg for every liter of water
This means
1 liter of water contains 0.13kg of salt
Now,
If 1 liter of water contains 0.13kg of salt
Then,
70 liters of water will contain 70 × 0.13 kg of salt
70 × 0.13 = 9.1 kg
Hence, the mass of salt in 70 liters of water from the Caspian Sea is 9.1 kg.
