Question

mass of 22.4 dm3 of n2 at stp is

Answer 1

Answer:

14

Explanation:

because one mol is equal to 22.4dm3

Answer 2

Given:

22.4 dm³ of N₂

To find:

Mass of 22.4 dm³ of N₂ at stp

Solution:

we know that

1dm³ = 1L

and 1L = 1mol = 22.4L

we are given 22.4 dm³ of N₂ = 1mol of N₂

Mass of 1mol of N₂ at STP = 14g

Hence, the mass of 22.4 dm³ of N₂ at STP = 14g
