A chemist prepares an aqueous solution of sodium hydroxide.  The solution contains 263.3 g of NaOH and has a volume of 750.0mL.  What is the molarity (moles/liter) of this solution? M=mols/L Answer with correct unit (1 point) and correct significant figures ( 1 point) All work must be shown for credit. No work=no credit. All work must in your own hand-writing.  

In this reaction, what volume of nitrogen gas can be produced by the reaction of 25.0 g of NaN3, if the temperature is 350 K and the pressure is 1.2 atmospheres? The formula mass of NaN3 = 65 g/mol. R= 0.08206 L*atm / K*mol
