The masses of salt and fresh water in the sea water at Protaras, Cyprus, are in the ratio 7:193. How many kilograms of salt are there in 1000 kg of sea water?

Answer :

Final answer:

In 1000 kg of seawater from Protaras, Cyprus, there would be approximately 35 kg of salt, given a salt to fresh water ratio of 7:193.

Explanation:

Firstly, let's understand the ratio. The ratio of salt to fresh water in the sea is 7:193. This signifies that in every 200 parts (7 parts of salt + 193 parts of fresh water), 7 parts are of salt. If we wanted to find out how many kilograms of salt are in 1000 kg of seawater, we would start by dividing 1000 kg by 200 to find out what 1 part of the sea water weighs. With that, let's calculate:

1 part = 1000 kg / 200 = 5 kg

So, if each part of our original ratio weighs 5 kg, the weight of the salt, which is 7 parts, would be 7 * 5 kg = 35 kg. So, in 1000 kg of seawater from Protaras, Cyprus, there would be approximately 35 kg of salt.
