Question

10g of NaCl is dissolved in 80g of water to form a solution .find the concentration of this solution .please answer​

Answer 1

Explanation:

10g NaCl means 10/58.5 mole NaCl i.e. 0.17 mole NaCl.

So,0.17 mole NaCl present in 80 g water

Therefore, 80g water contains 0.17 mole NaCl.

So, 1000g water contains 2.125 mole NaCl.

Hence,concentration of the solution is 2.125(m).
