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 atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons
