Question

How many moles of nitrogen are there in 6.8 liters at standard temperature and pressure?

Answer 1

Step-by-step explanation:

Given parameters:

Volume of gas at STP = 6.8L or 6.8dm³

Condition: Standard Temperature and Pressure

Solution:

For gases at standard temperature and pressure,

number of moles =
`(volume of occupied)/(22.4)`

number of moles =
`(6.8)/(22.4)` = 0.3moles
