For problem a. I did this: 53gKClO3/122gKClO3 * 3molesO2/2molesKCLO3 * 22.4L = 3562/244 = 14.6L O2 That's how I came up with 14.6L O2 Now I'm not sure about problem b. still. What do you think about for problem b.??

**Chemistry**

Hey Damon- Thanks for the tip on the molecules/mols. This will help. I'm so new at this stuff I'm trying to keep up.

**Chemistry**

So for problem a. I have the answer of 14.6L O2 which they gave us so we could learn how to solve it so I know 14.6L O2 is correct unless they gave me wrong answer. Being that your answer is a bit off from problem a. I'm thinking we may be a bit off on problem b? What do ...

Been stumped on this problem for a day now. 2KClO3-->2KCl+3O2 a) If 53.0g of potassium chlorate breaks down, what volume of oxygen is produced? For this one I got: 14.6L O2 b) How many grams of potassium chloride are produced from problem a? For the life of me I can't ...

**Chemistry**

I'll post it as a new problem. Its a Stoichemetric Problem that I'm completely stumped on. I think I have part of correct which i'd be happy to see if its correct so far or not.

**Chemistry**

Would you have another 5 minutes to help me one more problem I'm stumped on???

**Chemistry**

Ya and that equals 164. Thank you a ton for the help I've stomped on this whole problem for like a half an hour and I got lots more to do. This was my 2nd limiting reagent problem I've ever done so I'm still learning how to handle these.

**Chemistry**

Phosphorus is 31g.

**Chemistry**

3.) Cool that makes sense. So I believe this is how you convert mole to gram: .83 x 164g/mol = 136g Na3PO4 left over

**Chemistry**

Gotcha, thanks. Can you one of you guys see if I got 2 & 3 correct from the tips bob was giving me.

**Chemistry**

3. 200g Na3PO4 - 163 = 36g Ag3PO4??

**Chemistry**

Can you check my answer from your last tips: 1. Ok I think I understand. Still a little unsure tho where we're getting the 3 times the silver nitrate from for silver nitrate to be limiting reagent. 2. 1.18/3=.39 x 419 Ag3PO4 = 163g Ag3PO4 produced??

**Chemistry**

Hey bob- Here's what I got so far: 3AgNO3 + Na3PO4 ---> Ag3PO4 + 3NaNO3 Silver nitrate and sodium phosphate are reacted in equal amounts of 200. g each. How many grams of silver phosphate are produced? 1. What is the limiting? 2. How much silver phosphate is produced? 3...

**Chemistry**

Ok this is what I got so far: 200gAgNO3= 1.18 mole AgNO3 200gNa3PO4= 1.22 mole NaPO4 Then 419g Ag3PO4 x3 = 1257Ag3PO4 limiting reagent- Ag3PO4?

**Chemistry**

3AgNO3 + Na3PO4 ---> Ag3PO4 + 3NaNO3 Silver nitrate and sodium phosphate are reacted in equal amounts of 200. g each. How many grams of silver phosphate are produced? 1. What is the limiting? 2. How much silver phosphate is produced? 3. How much is in excess?
