# 1.00 g of oxygen react with 0.126 g of hydrogen to form "H"_2"O" and 1.00 g of nitrogen react with 0.216 g of hydrogen to form "NH"_3". Predict the amount of oxygen when it reacts with 1.00 g of nitrogen to form an oxide?

$\text{Mass of O" = 1.00 color(red)(cancel(color(black)("g N"))) × (0.216 color(red)(cancel(color(black)("g H"))))/(1.00 color(red)(cancel(color(black)("g N")))) × "1.00 g O"/(0.126 color(red)(cancel(color(black)("g H")))) = "1.71 g O}$
