The molecular weight of the gas is 14.9 g/mol. The approach to solving this problem is to determine the number of moles of gas present under those conditions for pressure and temperature, in that …

Notice the approximation we made earlier this question that the deuteron's weight is twice the weight of neutron the if we want the answer more accurately. Weight of an neutron = #1.674927351 (74)×10^ …

Explanation: 1 mole contains #6.022140857 × 10^"23"# (Avogadro's number) The molecular weight of #N_2O_3# is: 76.01 g/mol You have 28.3 g, so you have 28.3 / 76.01 = 0.37 mole Hence you have …

Let,their vapour density are rho_a and rho_b Now, we know, vapour density=2×Molecular weight So,we can write, rho_a=2×M_a (where M_a is the molecular weight of a ...

How do you calculate percent composition of a compound? How can I calculate the percentage by mass of sodium in sodium azide, NaN3 (s); used in automobile air bags? How can percent composition be …

Apr 9, 2018 · Now, the molecular weight of "CH"_4 is 16, and that of water is 18. Since the amount of methane combusting is 0.5 moles, we should get a mole of water, i.e. 18 gms of water under ideal …
