When it comes to calculating tonicity, 3.3% dextrose +0.3%NaCl can be though of as being the same as: 5% dextynse 0.3%NaCl 3.3% dextrose 0.9%NaCl

Answer:

The tonicity of a solution depends on the concentration of solutes in the solution.

In this case, 3.3% dextrose + 0.3% NaCl can be thought of as being the same as 0.9% NaCl, which is isotonic.

5% dextrose + 0.3% NaCl is hypotonic, because the concentration of solutes is lower than that of the intracellular fluid.

3.3% dextrose + 0.9% NaCl is hypertonic, because the concentration of solutes is higher than that of the intracellular fluid.

Therefore, 3.3% dextrose + 0.3% NaCl can be thought of as being the same as 0.9% NaCl, which is isotonic.
