Question

Find out the volume and mole in 56 g nitrogen at STP
Molecular weight of N, is 28 g​

Answer 1

Moles = 2 mol

Volume = 44.8 dm³

Step-by-step explanation:

From the question

mass of Nitrogen = 56 g

Molecular weight = 28 g/mol

To find the number of miles we use the formula

`n = (m)/(M)`

where

n is the number of miles

m is the mass

M is the molecular weight

So we have

`n = (56)/(28)`

We have the answer as

2 moles

To find the volume we use the formula

V = n × V(dm³)

where

V is the volume

n is the number of miles

V(dm³) is the volume of 1 mole of a gas at STP which is 22.4 dm³

So the volume is

V = 2 × 22.4

We have the answer as

44.8 dm³

Hope this helps you.
