The mass of NH3 will be 14,72 [tex]NH_{3}[/tex].
What is mass?
The mass of a thing is a measurement of how much matter it contains.
Calculation of mass:
Mass can be determined by the formula
d = m / v
m = mass, d = density and v = volume
It is given that, d = 0.92 g/cm3, volume = 80 cm3.
Now, put the value of given data in mass formula.
m = d × v
m = 0.92 × 80.0
m = 73.6 g.
Now,
It is known as 73.6 g = 100 %
X g = 20 %
X = (73.6 g × 20 )/ 100
X = 14,72 [tex]NH_{3}[/tex].
Therefore, the mass of NH3 will be 14,72 [tex]NH_{3}[/tex].
