Answer:
Approximately .
Explanation:
Look the relative atomic mass of each element on a modern periodic table:
- H: 1.008.
- N: 14.007.
- O: 15.999.
- C: 12.011.
Calculate molar mass values from relative atomic mass:
.
.
Calculate the number of moles of each reactant:
.
.
One of the two reactants might be in excess. To find the limiting reactant, calculate the ratio .
.
However, in the equation, the ratio between the coefficient of and is .
Since , the species on the numerator ( in this case) is the limiting reactant.
As a result, should be calculated from , not .
In the equation, the coefficient ratio .
Apply this ratio:
.
Calculate using its molar mass value:
.
Note: the last digit might be inaccurate due to rounding errors.
