### A compound that contains only nitrogen and oxygen is

Nov 09, 2015 · Empirical formula is NO_2, and the molecular formula is N_2O_4, dinitrogen tetroxide. In 100* g of this compounds there are 30.4* g N, and the balance O. We divide thru by the atomic masses in order to approach the empirical formula:(30.4*g)/(14.01*g*mol^-1) = 2.17*mol*N; (69.6*g)/(16.0*g*mol^-1) = 4.35*mol*O. After we divide thru by 2.17, we get an empirical formula of

### Calculating RMMs of Compounds (the Relative Molecular

Notice that it doesn't matter how complicated the formula is, or whether you know what the compound is or have never seen it before in your life, you just work out the answer step by step. Then you check it again, in case you hit the wrong key on the calculator, or got the brackets wrong. Calculating reacting masses of reactants & products For this see empirical formula and formula mass of a compound from reacting masses. Reacting mass calculation Example 6a.2. The neutralisation of sulfuric acid with sodium hydroxide. 2NaOH + H 2 SO 4 ==> Na 2 SO 4 + 2H 2 O (atomic masses Na = 23, O = 16, H = 1, S = 32)

ChemTeam:MolarityIn the above problem, 58.44 grams/mol is the molar mass of NaCl. (There is the term "formula weight" and the term "molecular weight." There is a technical difference between them that isn't important right now. The term "molar mass" is a moe generic term.) To solve the problem:Step One:dividing 58.44 grams by 58.44 grams/mol gives 1.00 mol.

### Relative Humidity

For an air temperature of C = F, the saturated vapor density is gm/m 3 (Calculated by an empirical fit to published data.) If the actual humidity in the air is gm/m 3, then the relative humidity is %. With this amount of humidity, the dewpoint is approximately °C = °F. Caution! The empirical fit used is only reliable up to 40°C. Saturated Vapor Pressure - HyperPhysics ConceptsThe boiling point is defined as the temperature at which the saturated vapor pressure of a liquid is equal to the surrounding atmospheric pressure.For water, the vapor pressure reaches the standard sea level atmospheric pressure of 760 mmHg at 100°C. Since the vapor pressure increases with temperature, it follows that for pressure greater than 760 mmHg (e.g., in a pressure cooker), the
