How many moles of nitrogen are there in a 16,500 mL sample of nitrogen at STP?

Answer : The number of moles of nitrogen present are, 0.737 mol

Explanation :

As we know that at STP, 1 mole of substance occupies 22.4 L volume of gas.

As per question,

As, 22.4 L volume of nitrogen gas present in 1 mole of nitrogen gas

Conversion used : 1 L = 1000 mL

Or, 22400 mL volume of nitrogen gas present in 1 mole of nitrogen gas

So, 16500 mL volume of nitrogen gas present in mole of nitrogen gas

Therefore, the number of moles of nitrogen present are, 0.737 mol

the answer for sodium is 0.186

the answer for rubidium is 0.251

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
