n = number of particles/molecules/ionsN = No. of molesNA = Avagadro's numberI think you just mixed up the definitions of N and n. Logged Tonight I’m going to party like it’s on sale for $19.99!- Apu Nahasapeemapetilonsteph_r Regular Member Posts: 42 Mole Snacks: +2/-0 ...
16.04g / 6.022x10^23 molecules atomic mass doesn't apply... methane is a molecular not atomic substance molecular mass = 16.04 AMU / moleculemake sure you're using molar mass, atomic mass, molecular mass, isotopic mass, relative atomic mass, etc correctly and that you are rock solid on ...
2 S(s) + 2 O2(g) → 2 SO2(g), ΔHf= 2(-326.8 kJ/mol) Now you have two extra S's and one extra C molecule on the reactant side that you don't need. Thethird reactionalso has two S's and one C on thereactantside. Reverse this reaction to bring the molecules to the p...
Step 1- Determine thenumber of molesof each solution in order to be able to calculate the mole fraction of the components. From theperiodic table, the atomic masses of the carbon and hydrogen atoms in hexane and benzene are: C = 12 g/mol H = 1 g/mol Use the molecular weights to fin...
molar mass of H2= 2 grams molar mass of O2= 32 grams molar mass of H2O = 18 grams How much H2O is formed from 20 grams H2? grams H2O = 20 grams H2x (1 mol H2/2 g H2) x (1 mol H2O/1 mol H2) x (18 g H2O/1 mol H2O) ...
