Question

What volume of 0.35M `SrCl_2`is needed to make 158 ml of 0.85M `SrCl_2` solution?

Answer 1

This question has been improperly proposed.

Explanation:

Normally, `C_1V_1=C_2V_2`; but here we are NOT DILUTING, and `C_2` is MORE concentrated than `C_1`. We cannot get to `C_2` by dilution.

Would you recheck the question?
