Acell with a concentration of 1.5% nacl is immersed in a solution with a concentration of 5.5% nacl. what will happen to the cell after being immersed in the solution for many hours?

This question depends on whether its an animal cell or a plant cell
For animal cell, the water molecules will move from the cell sap out to the solution by net movement of osmosis through a partially permeable membrane. it eventually becomes crenated.
For plant cell, water molecules will move from cell sap to the solution and eventually turns flaccid or plasmolysed

A.(nh4)(2co3)is the correct answer 

Sorry i dont understand the question can you rephase it?
