Best ResponseYou've already chosen the best response.1Do you mean decomposes, \[2HgO > O_2 + H_2\] this is your chemical equation. We're given molar mass for HgO which is 216.59 mol Molar mass of O2 is 32 g/mol, and we're given 250 g of oxygen We need to find moles of oxygen so we just need this formula \[m = n \times M\] where n represents number of moles, m is the mass, and molar mass is M.\[n = \frac{ m }{ M }\] we're given both the mass and molar mass of oxygen, so just plug in the values and you're done.
