Exercise 11
Hints
- Ignore this one for the mo’.
- 0.6 moles of Cl– implies we have how many moles of Na+ ions as a result of NaCl? 0.6 moles of SO42- implies we have how many moles of Na+ ions as a result of NaSO4? Add them together…
- a) Start with the carbons; b) Go mass C4H10 → moles C4H10 → moles N2 → vol. N2.
- a) Work out the numbers of moles of Zn and H2SO4 and do a “what if?”; b) Use the limiting reagent to get a number of moles then find the mass.
