First find molar mass of NH_3

$\\ \tt\longmapsto NH_3$

$\\ \tt\longmapsto 14g/mol+3(1g/mol)$

$\\ \tt\longmapsto 14+3$

$\\ \tt\longmapsto 17g/mol$

$\\ \tt\longmapsto No\:of\;moles=(Given\:mass)/(Molar\;mass)$

$\\ \tt\longmapsto Given\:mass=No\:of\:moles* Molar\:mass$

$\\ \tt\longmapsto Given\:mass=2.5(17)$

$\\ \tt\longmapsto Given\:mass=42.5g$
