Which would be the best way to represent the concentration of a 1 point 7 5 cap m cap k sub 2 CrO sub 4 solution?

The concentration is given as 1.75 M, and M means moles of solute per liter of solution. Brackets around K₂CrO₄ indicate its concentration, so [K₂CrO₄] = 1.75 M correctly represents the solution. A gives a percent concentration, which is a different unit.
