Condensation as it is the change of the physical state of matter from gas phase into liquid phase
How am I supposed to help you if there's not picture of what the problem is
Answer:
2M
Explanation:
M=mol/L
1. Find moles of CoCl2
mass of substance/molar mass = 130/129.833 = 1.001 mol
3. Substitute in molarity equation
M=(1.001/0.5)
M= around 2M
I believe that the answer is D.
I hope this helps. :)
