![]() Yellow light emitted from a sodium lamp has a wavelength (2) of 580 nm. Write the complete symbol for the atom (X) with the given atomic number (Z) and atomic mass (A) How many protons and neutrons are present in the following nuclei No, the answer will not change upon changing the temperature and pressure because only the number of protons and mass of protons are involved. of protons present in one molecule of NH 3 = 7 + 3 = 10. Calculation of total number and mass of protons Gram molecular mass of ammonia (NH 3) = 17 g = 17 × 10 3 mgġ7 × 10 3 mg of NH 3 have molecules = 6.022 × 10 23 Calculation of total number ofNH 3 molecules of neutrons present in one atom (C-14) of carbon = 14 – 6 = 8 Calculation of total number and tatal mass of neutrons Calculation of total number of carbon atoms of electrons present in one molecule of CH 4 = 6 + 4 = 10 (i) One mole of methane (CH 4) has molecules = 6.022 × 10 23 Will the answer change if the temperature and pressure are changed ? (iii) Find (a) the total number and (b) the total mass of protons in 34 mg of NH 3 at STP. (Assume that mass of a neutron = 1.675 × 10 -27kg). (ii) Find (a) the total number and (b) the total mass of neutrons in 7 mg of 14C. (i) Calculate the total number of electrons present in one mole of methane. (ii) One mole of electrons = 6.022 × 10 23 electrons (ii) Calculate the mass and charge of one mole of electrons.ĩ.1 × 10 -28 g is the mass of = 1 electron (i) Calculate the number of electrons which will together weigh one gram.
