# What is the molar quantity of ammonia associated with a 1.9*g mass of same?

And to get the $\text{moles of ammonia}$, we solve the quotient.....
$\text{Moles of ammonia"-="Mass of ammonia"/"Molar mass of ammonia}$
$\equiv \frac{1.9 \cdot g}{17.03 \cdot g \cdot m o {l}^{-} 1} = 0.112 \cdot m o l$ $\text{ammonia}$....is this calculation dimensionally consistent; why? What molar quantity of hydrogen does this quantity represent?
