Here’s the question! Silver nitrate and sodium phosphate are reacted in equal amounts of 200. g each. How many grams of silver phosphate are produced?

What’s to do first? Set Up An Equation Turn off the computer Do a mole to mole conversion

Wrong!!! Go Back

Good Job! …but what is the correct equation? AgNO₃ + Na₃PO₄ → Ag₃PO₄ + NaNO₃ FeNo₃ + Cl₃PO₄ → Fe₃PO₄ + ClNO₃ AgNO₄ + Na₄PO₃ → Ag₄PO₃ + NaNO₄

Correct! Now balance it! 3AgNO₃ + Na₃PO₄ → Ag₃PO₄ + 3NaNO₃ 3AgNO₃ + 4Na₃PO₄ → Ag₃PO₄ + 6NaNO₃ AgNO₃ + Na₃PO₄ → Ag₃PO₄ + NaNO₃

Great! Now tell me, what kind of problem is this? A regular one Limiting reagent

Yes, limiting reagent! Okay what’s the first step? 200. g AgNO₃ g Na₂PO₄ g AgNO₃ g Na₂PO₄ GFM

Right. What’s the next step? 200. g AgNO₃ X 200. g Na₂PO₄ X Mole to mole conversion GFM Gram to Liters conversion

Wonderful! Next..? 200. g AgNO₃ g Na₂PO₄ X X 1 mol g AgNO₃ 1 mol g Na₃PO₄ X X Mole to mole conversion Done! Multiply by 6.02 x 10 to the 23

You’re on a roll! Neeexxxtt g AgNO₃ g Na₂PO₄ mol AgNO₃ g AgNO₃ X 1 mol Na₃PO₄ g Na₃PO ₄ X 1 mol Ag₃PO₄ mol AgNO₃ X X 1 mol Ag₃PO₄ mol Na₃PO₄ Okay, now we’re done.One more GFM Convert to molecules

So close! 200. g AgNO₃ g Na₂PO₄ mol AgNO₃ g AgNO₃ 1 mol Na₃PO₄ g Na₃PO₄ 1 mol Ag₃PO₄ mol AgNO₃ 1 mol Ag₃PO₄ mol Na₃PO₄ X X X X g Ag₃PO₄ mol Ag₃PO₄ g Ag₃PO₄ mol Ag₃PO₄ X X Solve This is the answer

How many grams of silver phosphate are produced? 511 g 164 g 675 g

You won!
