Two different compounds are obtained by combining nitrogen with oxygen. the first compound results from combining 46.7 g of n with 53.3 g of o, and the second compound results from combining 17.9 g of n and 82.0 g of o. calculate the ratio of the mass ratio of o to n in the second compound to the mass ratio of o to n in the first compound. express your answer numerically.

One of the hopes for solving the world's energy problem is to make use of the fusion reaction 21h +31h --> 42he + 10n + energy how much energy is released when 1 mol of deuterium is fused with 1 mol of tritium according to the above reaction? the masses of the atoms and the neutrons are as follows: 21h = 2.0140 amu 31h = 3.01605 amu 42he = 4.002603 amu 10n = 1.008665 amu. the speed of light is 2.9979 x 108 m/s.
