Question

calculate number of miles and molecules of ammonia (NH3)gass in a volume 44.8dm³ of it measured at STP​

Answer 1

Answer:

when u r doing such problems always check for condition

since it is stp

V when gas has. 1 mole is 22.4L/dm^3

so by unitary method 44.8 will have 2 moles

now since u got 2 moles

u need to find no.of molecules

1 mole has 6.022*10^23 molecules (Avogadro number)

2 mole will have *2 Avogadro number
