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.
