What is quantity?

In chemistry, quantity refers to the amount of a substance that is present in a sample or involved in a chemical reaction. The two most common units used to express quantity in chemistry are moles and grams.

Let the initial quantity of water in the container be x kg.

Then, after 5 kg of water is added, the total quantity of water in the container becomes x + 5 kg.

After 3 kg of water is taken out, the total quantity of water in the container becomes (x + 5) - 3 = x + 2 kg.

Given that finally there is 7 kg of water in the container. Therefore, we have:

x + 2 = 7

Solving for x, we get:

x = 7 - 2 = 5

Therefore, the initial quantity of water in the container was 5 kg. Therefore, the answer is (a) 5 kg.
