• diluted.

• saturated.

• supersaturated.

• unsaturated.

What is it about the water molecule that makes it a great solvent?

• water demonstrates polarity; a partial charge on each side of the molecule
• due to its molecular formula
• it has a liner molecular shape

What is the correct formula to solve for the Molarity of a solution that has .4 moles of HCl in 9.5 L of solution?

• M = 9.5 L / .4 mol
• M₁V₁=M₂V₂
• M = .4 mol / 9.5 L
• none of the other choices
