1.00g of oxygen combine with 0.126 g of hydrogen to form H2O. 1.00 g of nitrogen combie with 0.216 g of hydrogen to form ammonia. Predict the weight of oxygen
To predict the weight of oxygen, we need to use the given information about the reactants and products of two different chemical reactions.
Let's start by finding the molar ratio between hydrogen and oxygen in both reactions.
In the first reaction, we have 1.00 g of oxygen combining with 0.126 g of hydrogen to form water (H2O). To find the molar ratio, we need to convert these masses to moles by dividing them by their respective molar masses. The molar mass of oxygen (O) is 16.00 g/mol, and the molar mass of hydrogen (H) is 1.01 g/mol.
Moles of oxygen (O) = 1.00 g / 16.00 g/mol = 0.0625 mol
Moles of hydrogen (H) = 0.126 g / 1.01 g/mol = 0.125 mol
The molar ratio between hydrogen (H) and oxygen (O) in this reaction is 0.125 mol H : 0.0625 mol O (or 2 mol H : 1 mol O).
In the second reaction, we have 1.00 g of nitrogen combining with 0.216 g of hydrogen to form ammonia (NH3). Using the same steps as above:
Moles of nitrogen (N) = 1.00 g / molar mass of nitrogen
Moles of hydrogen (H) = 0.216 g / molar mass of hydrogen
Note: We didn't provide the molar mass of nitrogen, so I can't calculate the moles of nitrogen without that information.
Once you have the molar ratio between hydrogen and oxygen in the second reaction, you can use it to predict the weight of oxygen when given the weight of hydrogen.
