Question

To make a 2.0-molar solution, how many moles of solute must be dissolved in 0.50 liters of solution?

0.25 moles solute

0.50 moles solute

1.0 mole solute

2.0 moles solute

Answer 1

I am a bit confused, I think it might be C.

Answer 2

2.0 is your concentration or your molarity (M) the equation is:
M=mols of solute/volume (Lets say moles of solute is represented by x)
So 2.00M=x/0.5L
2*0.5=x
So yes it is C, 1.0mols of solute
