How many moles of n2o5 are needed to produce 7.90 g of no2? 2n2o5 = 4no2 + o2

0.08585 moles of is needed to produce 7.9 grams of

Explanation: Moles is calculated by using the formula:

Molar mass of = 46 g/mol

Number of moles of = 0.1717 moles

For the given chemical reaction:

By Stoichiometry,

4 moles of is produced by 2 moles of

So, 0.1717 moles of is produced by = = 0.08585 moles of

Hence, moles of is 0.08585 moles.

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
