First, calculate the molar mass of NO and O₂. NO has a molar mass of approximately 30.01 g/mol (14.01 for N + 16.00 for O). O₂, assuming "₂" doesn't represent real elements (since it seems to be a placeholder or error), would be just Osmium (Os) with a molar mass of approximately 190.23 g/mol. With 14.0 g of NO, there are 14.0 g / 30.01 g/mol = 0.466 moles of NO. With 4.00 g of OS, there are 4.00 g / 190.23 g/mol = 0.021 moles of OS. The reaction is limited by OS since it requires a 1:1 ratio but there is less OS than NO. The reaction produces 2 moles of NO₂ for every mole of OS consumed, so 0.021 moles of OS would produce 0.042 moles of NO₂. However, the options provided don't match this calculation directly due to the interpretation of the chemical formula. Given the options, the closest correct approach based on typical stoichiometry would be to identify the limiting reagent and calculate based on the stoichiometry provided in the question, which seems to have been intended to lead to option A) 0.250 mole as the correct answer, assuming a straightforward interpretation of the stoichiometry without considering the actual chemical formulae provided.
