202.0 g of Borax (Na2B4O7) is dissolved in 400. mL of water. The density of water is 1.00 g/mL. Calculate the molarity of the solution (moles of solute/ liters of solution). Round molar masses to whole numbers, use appropriate significant figures, and show your work.

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.
