Answer:

Is there a question here? I presume you want the molar quantity of ammonia............

Explanation:

And to get the #"moles of ammonia"#, we solve the quotient.....

#"Moles of ammonia"-="Mass of ammonia"/"Molar mass of ammonia"#

#-=(1.9*g)/(17.03*g*mol^-1)=0.112*mol# #"ammonia"#....is this calculation dimensionally consistent; why? What molar quantity of hydrogen does this quantity represent?
