Answer: Molar mass of 
 is 17.03 g
 is 17.03 g
Step-by-step explanation:
Molar mass is defined as the mass in grams of 1 mole of a substance. 
 S.I Unit of Molar mass is gram per mole and it is represented as g/mol. 
It is found by adding the atomic masses of all the elements present. 
 Atomic Mass of Nitrogen (N) = 14.007 g 
 Atomic Mass of Hydrogen (H) = 1.008 g 
 Molar mass of 
 = 1(14.007)+3(1.008) g = 17.03 g
 = 1(14.007)+3(1.008) g = 17.03 g
