Tetraphosphorus hexoxide is formed by the reaction of phosphorus with oxygen gas if a mixture of 67.1g of phosphorus and 58.4 g of oxygen produce 70.0 grams of P4O6 what is the percent yield for this reaction? (P 4 + 3 O2–> P4O6)

Used the balanced equation 2h2+ o2 - -> 2h2o. if you have 7.2 grams of o2 , how many grams of h2o can you produce ?

Can someone me with 1 to 4 plz. fast
