NCERT DC Pandey Sunil Batra HC Verma Pradeep Errorless. (i) State the ideal gas equation and use it to calculate the total number of moles of nitrogen and oxygen formed. one mole of oxygen should = 16 but oxygen is a diatomic gas so when referring to OXYGEN in EMPIRICAL FORMULA and calculating moles do we see oxygen as a diatomic gas or do we ignore that and say that one mole of oxygen = 16g. Oxygen is also diatomic, so we multiply 16 by 2 to find the oxygen in our sample has a molar mass of 32. The volume of oxygen given out at the anode was 112cm 3 measured at s.t.p. This was calculated by multiplying the atomic weight of hydrogen (1.008) by two and adding the result to the weight for one oxygen (15.999). Mass of bromine = 0.6 × 80 = 48 g. To Calculate Mass of a Molecule and Atom: Calculate the following. One mole of any gas has a volume of 24 dm 3 or 24,000 cm 3 at rtp (room temperature and pressure). Therefore, mass of oxygen liberated = 0.6g. 8g/(16g/mol) = 0.5 mol. (1 u is equal to 1/12 the mass of one atom of carbon-12) Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol. From the periodic table we see the atomic weight of hydrogen is 1.0079 and the atomic weight of oxygen is 15.9994.
