mass of o2 in kg

# mass of o2 in kg

As we know in the ultimate analysis of fuel we determine the mass of various combustible elements in the fuel. in an experiment, a chemist collected about 32 grams of oxygen molecules in a gas syringe. One atom of O =1 x Atomic mass = 1 x 16 = 16 gms= 16/1000 = 0.016 kg A molecule of O2= 2 x At. To convert a quantity of a substance or material expressed as a volume to mass we simply use the formula: mass = density × volume . About Oxygen; 1.429 kilograms [kg] of Oxygen fit into 1 cubic meter; 0.000826014 ounce [oz] of Oxygen fits into 1 cubic inch; Oxygen weighs 0.001429 gram per cubic centimeter or 1.429 kilogram per cubic meter, i.e. In kilograms, the molar mass of a hydrogen atom can be written as 0.001 kilograms per mole. The volume of air is 100/21 = 4.76 times that of the oxygen . In grams, the mass of an atom of hydrogen is expressed as 1.67 x 10-24. round the coefficient to the nearest hundredth) and calculate the mass of one oxygen atom if an oxygen molecule consists of 2 atoms. Minimum quantity of air required for complete combustion of 1 kg of fuel is given by: Determination of the Flue Gas Analysis by Mass and by Volume: Mass = 2 x 16 = 32gms= 32/1000 = 0.032 kg According to table 5.1 on page 155 of Atmospheric Science: An Introductory Survey By John M. Wallace, Peter V. Hobbs (table can be seen here on Google Books) dry air is composed of: Nitrogen: 78.084% Oxygen: 20.946% Argon: 0.934% Carbon dioxide: 0.03% If you add these up you get: 78.084 + 20.946 + 0.934 + 0.03 = 99.994% (the remaining material 100 - … Instant free online tool for Atomic mass unit to kilogram conversion or vice versa. For the Earth, half the mass of the atmosphere lies below about 5.5 km altitude, and 99 per cent below 30 km. The atmosphere is mostly made up of oxygen and nitrogen in their diatomic forms. (write your answer in scientific notation. 1) NH3 + O2 --> NO + H2O Balanced = 4NH3 + 5O2 = 4NO + 6H2O ? From Avagadro: 1mol of oxygen is in 4.76 mol of air . About Oxygen; 1 cubic meter of Oxygen weighs 1.429 kilograms [kg] 1 cubic inch of Oxygen weighs 0.000826014 ounce [oz] Oxygen weighs 0.001429 gram per cubic centimeter or 1.429 kilogram per cubic meter, i.e. 28.96 g / mol This is a fun question. Also, explore tools to convert Atomic mass unit or kilogram to other weight and mass units or learn more about weight and mass … In 1 kg of fuel: Carbon is 0.83 kg, hydrogen 0.05 kg, oxygen 0.02 kg and sulphur 0.002 kg. For each reaction, calculate the mass (in kg) of the first reactant that is required to react completely with 657 kg of the second reactant. 1 volume oxygen is in 4.76 volumes air . 3)Nitrogen dioxide and water react to form nitric acid and nitrogen oxide. How to convert 1 liter of oxygen (liquid) to kilograms. oxygen gas and liquid unit conversion tables - weight, gas volume, liquid volume (pounds, kilograms, standard cubic feet, standard cubic meters, gallons, liters) Without chemical processes involving several of the atmospheric gases, life could not exist. The mass of an atom of hydrogen can also be expressed in molar mass units as one gram per mole. 2) Nitrogen oxide and molecular oxygen combine to give nitrogen dioxide. 32g oxygen is in 4.76*29 = 138g air. assume that there are 6.02x10^23 molecules in the syringe. Molar mass of oxygen = 32g/mol . Air is 21% oxygen by volume. We want to calculate the mass in kilograms from a volume in liters. (write your answer in scientific notation. The average molar mass of air = 29g/mol . An amu is … The Atomic mass unit [u] to kilogram [kg] conversion table and conversion steps are also listed.
