What is the maximum amount of moles of p2o5 that can theoretically be made from 136 g of p4 and excess oxygen

The maximum number of moles of theoretically made is 2.194 moles.

Explanation:

To calculate the number of moles, we use the equation

Given mass of = 136 g

Molar mass of = 123.9 g/mol

Putting values in above equation, we get:

The chemical equation for the formation of follows:

Oxygen is present in excess, so it is considered as an excess reagent.

is considered as a limiting reagent because it limits the formation of product.

By Stoichiometry of the reaction:

If 1 mole of is producing 2 moles of

So, 1.097 moles of will produce = of

Hence, the maximum number of moles of theoretically made is 2.194 moles.

answer: they produce more slow than unicellular organisms.
