Web2 feb. 2024 · 2 Answers Sorted by: 3 It says that 2 moles of of C H X 3 O H release 1354 kJ. This is the same as saying that 1 mole of of C H X 3 O H releases 677 kJ. Here I just divided the 1354 by 2 to obtain the number of the energy released when one mole is burned. This way it is easier to do dimensional analysis.

Web14 jun. 2024 · We can determine the number of moles of water required for 36 grams. 36g/18 g/mole = 2 moles of water. We need 1/4 that number of moles of propane, so moles propane = 0.5 moles. Times it's molar mass of 44 g/mole, we find that we only need 11 grams of propane to produce 36 grams of water. Bob WebIf 1 N 2 requires 6 Na, then if you had 5 N 2 you would need 6 x 5 = 30 moles Na. b. If I had 2 moles of sodium, how many grams of sodium nitride would it react with? 6 moles sodium 2 moles sodium nitride. But you only have 2 moles sodium (1 third!), so you would have 1/3 x 2 moles Na 3 N = 0 moles of sodium nitride. optometrist hiawassee ga
