PLEASE CHECK FOR ACCURACY!!!!
Your answer
1. Given the data below determine the mass of the dried precipitate.
*
Please do not add units and make sure your answer is rounded to 3 decimal places.
Your answer
2. Please convert the grams of the precipitate to moles.
*
Please do not add units and make sure your answer is rounded to 3 sig figs.
Your answer
3. In every one mole of the precipitate how many mole of Carbonates are there?
*
1
2
3
4
6.02 x 10^23
4. How many moles of carbonate ion are there in the precipitate?
*
Do not add units. The significant figures you start with will be the amount you finish with.
Your answer
5. How many moles of carbonate ions are in one mole of the unknown original metal carbonate (M2CO3)?
*
1
2
3
4
6.02 x 10^23
6. Given your answer to question 4, moles of carbonate ions in the precipitate, determine the number of moles of unknown salt, M2CO3.
*
Do NOT add units. The significant figures you start with will be the amount you finish with.
Your answer
7. Calculate the experimental Formula Mass (same as molecular mass) of the unknown metal carbonate.
*
Don't we have the mass of the original salt in our data table. Isn't that the 1st measured value of the lab. Please round to 4 significant figures and do NOT add any UNITs!
Your answer
8. Calculate the formula mass of lithium carbonate.
*
Please do NOT add any units and round to nearest whole number.
Your answer
9. Calculate the formula mass of sodium carbonate.
*
Please do NOT add any units and round to nearest whole number.
Your answer
10. Calculate the formula mass of potassium carbonate.
*
Please do NOT add any units and round to nearest whole number.
Your answer
11. Which is the most unavoidable error in experiments with precipitation analysis?
*
Splattering of the salt
oxides forming
other oxidation agents
some of the precipitate not being collected
overfeeding the gorilla
12. How does the error in question 11 affect your experimental Formula Mass?
It has no effect
It inflates it.
It deflates it.
