Question

2.24 litres of dinitrogen content how many mass ?

Answer 1

ANSWER:-

We know,

mass of di-nitrogen (N2) = 28 gm.units

given volume = 2.24 litres

Standard Time Pressure (STP) = 22.4 litres

Therefore,

mass of di-nitrogen =

$= > \frac{mass}{stp} \times given \: volume \\ = > \frac{28}{ \cancel{22.4}} \times \cancel{2.24} \: 0.1 \\ = > \boxed{2.8 \: units}$

Hence, done.
