Solution X contains 50 g of salt in 100g of water and solution Y contains 100g of salt in 200g of water.

If the amount of the solute present is little for a given volume of solution, the solution is said to be dilute. If the amount of the solute present is more for a given volume of solution, the solution is said to be concentrated. Concentration is the mass of solute dissolved in the given volume of the solution.

Solution X contains 50 g of salt in 100g of water and solution Y contains 100g of salt in 200g of water. Which of the following can be true based on the above information ? 

A) Solution X has the same concentration as solution Y. 

B) Solution X is more concentrated than solution Y. 

C) Solution X is more dilute than solution Y. 

D) Concentration of X cannot be compared with that of solution Y as their volumes are different.
