How many g of NAOH (40 grams in one Avogadro's Number of the molecules) are required to prepare 500 mL of 0.250 mole? 500 mL is 1/2 of a liter and 0.250 is 1/4 of a full Avogadro, so 1/2 x 1/4 x 40 = the answer

  • see this is more easy : .250 M*.5L*Formula weight= 5 g of NaOH student from Puerto Rico of chemistry take care

  • probably if yo take .250M and * by 500mL will obtain the mol of NAOH later * by the Formula Weight will give you the grams you need to weight to prepared the desired solution

  • Not the best explanations, but k

  • hah. you wouldn't live more than 25 years without this stuff. thats how much you need it.

  • it would have been easier to know that Molarity= moles of solute/liters of solvent.... then find the moles of solute and convert that to grams....

  • useless. u need to organize ur self

  • when will we need this in life???

  • This is badass I'm gonna submit problems!

  • much easier to follow than my bullox teacher.
