Question

1.6 moles of phosphorus, P8 reacts with oxygen gas to form tetraphosphorus decoxide. How many grams of P4O10 are formed?P8 + 5O2 --> 2P4O10

Answer 1

The balanced chemical reaction are as follows:

P8 + 5O2 --> 2P4O10

We are given the amount of P8 to be used in the reaction. We use this to calculate what is asked. We do as follows:

1.6 mol P8 ( 2 mol P2O10 / 1 mol P8 ) ( 283.89 g / mol ) = 908.45 g P4O10 produced
