The gram of nitric acid is 30.82 grams of HNO3.
The molar mass of nitric acid is derived from the atomic mass of the element and its corresponding quantity. Percent Yield is a calculation that compares the amount of product you are actually producing with the amount of product you were calculated to be producing.
Calculation:-
Percentage yield = 76%
mass of NO2 consumed = 45 g
percentage yield = observed/actual ×100
obtained mass = 75× 45÷100
= 135/4
=30.82 gram
All real laboratory reactions always produce slightly less product than calculated. The yield rate measures how close you can get. Theoretical yields are calculated based on the stoichiometry of the chemical formula. Actual yield is determined experimentally. The yield rate is determined by calculating the ratio of actual yield/theoretical yield. Percent yield is a calculated number that indicates the percentage difference between the theoretical yield and the actual yield of the experiment.
