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.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
