This question is for a high school chemistry class. This question was assigned friday, may 19th. the first person to report to class before school monday, may22nd is promised 10 % on the final exam. The question goes as following:

You are given three flasks containing different substances in aqueous solution.

1.00 M AgNO3, 1.00 M NaClO3, and 1.00 M Na3PO4.

You have access to the following pieces of equipment:

1 evaporating dish
1 funnel
1 hot plate
1 stirring rod
1 triple beam balance
1 graduated cylinder
2 empty beackers
2 pieces of filter paper


To solve the equation I must describe and show all calculations for the steps I would take to produce 50 grams of solid crystal sodium nitrate. (NaNO3)


 I dont have much to offer other than as many gmail invites as you can take, but i would be extremeley grateful for an answer or help solving this problem. If you have the knowlege it requires to solve it. please describe and show the calculations neatly so I can earn the extra credit. Thank you very much and any help is greatly appreciated.

Write a balanced reaction: AgNO3 + Na3PO4
Calculate, how many mole equivalent for  50 g NaNO3
Do reaction
Filtate solid Ag3PO4
Remowe water from filtrate

alright lets dumb this down to a tenth grade level. perhaps a little more in detail. I'm not asking for the answer, just a how to.

How hard is to measure the required volume of reagents, then mix them in a beaker?

Can somebody please explain the do reaction part in detail perhaps with an answer. Time is ticking!

You can do a reaction by mixing two reactants together in a suitable solvent and stirring.
There is no science without fancy, and no art without facts.

to be more specifice i need to know how much of each reactant to be mixing. if somebody could answere me that, i'm set.

As the others have already said start by writing a balanced equation...

done that, im on step three of the equation which is to do the reaction. i need somebody to explain the whole step.

Well that is what I am trying to do, so first step is write the balanced equation for me....

AgNO3+Na3PO4=NaNo3+AgNa2PO4

Ok so first you need the correct equation:

3AgNO3 + Na3PO4 = Ag3PO4(s) + 3NaNO3

And I think you said you want to make 50g of sodium nitrate so you need to calculate how many moles of sodium nitrate that is and use this number and the ratios from the balanced equation to work out how many moles of reactants you need for this. You can then convert this to how much 1 M solution you need.
There is no science without fancy, and no art without facts.

this is my final conclusion tell me what you think.
