Question #30c24
1 Answer
Your tool of choice for stoichiometry problems is the mole ratio.
For your balanced chemical equation, you have
Notice that you need
For the compounds involved in your reaction, you will always have the same ratios between the number of moles of each that react.
So, if you have 5.64 moles of oxygen that react, you'd need
Likewise, if 3.27 moles of oxygen react, you will produce
For the third scenario, you were given mass, not moles. To go from mass to moles, use ammonia's molar mass, which represents the mass of 1 mole of the substance
Once you have the moles, use the mole ratio that exists between ammonia and water
