Question
Similar to a lab described in class, a small amount of marble chips (CaCO3) are placed
inside a flask and weighed (as seen in 1 above).
Nitric acid (HNO3) is added with a buret causing a reaction to occur (as seen in 2&3
above).
After the reaction ends, the liquid is drained away, the remaining chips rinsed and dried
(seen in #4 above).
The data collected is as follows:
* Mass of flask with chips before reaction: 120.15 g
Mass of flask with chips after reaction: 114.09 g
Buret reading before acid is added: 45,34 mL.
Buret reading after acid is added: 22.01 mL
Use the above data to determine the molarity of the nitric acid (HNCO) if the equation for
the reaction is:
2HNO3(aq) + CaCO,(s) H,0(1) + CO2(g)- Ca(NO.)>(aq)
(round your final answer to 2 decimal places)

When solving the problem below, what step would you take first?
If 2.5L of 0.515M Fe(NO3)3 solution react, how many grams of Fe(OH); will be produced?
Fe(NO3)a(aq) + 3NAOH(aq) → Fe(OH)3(s) + 3NaNO3(aq)
(You do not need to solve the problem!)
