Question

If 3.90 g of CuNO3 is dissolved in water to make a 0.840 M solution, what is the volume of the solution in milliliters?

Answer 1

49.6ml

Step-by-step explanation:

formula: L solution = mols/M

First convert CuNO3 to mols by using its molar mass. 93.56 g

then plug into the formula I gave. 3.90 g CuNO3=0.0417 mols
