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.

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
