If the percent yield for the following reaction is 60. 0%, and 45. 0 g of no2 are consumed in the reaction (with an excess of h2o), how many grams of nitric acid, hno3(aq), are produced?.

Respuesta :

The experimental yield of nitric acid is  24.648 g if percent yield for the reaction is 60%.

Nitrogen dioxide mass, given, is 45.0 g

Nitrogen dioxide has a molecular mass of 46 g/mol.

For the chemical formula given:

Nitrogen dioxide moles are equal to 45/46 or 0.978 g/mol.

Using the reaction's stoichiometry:

2 moles of nitric acid are produced from 3 moles of nitrogen dioxide.

Nitric acid will therefore be produced by 0.978 moles of nitrogen dioxide.

Now, using equation 1 to calculate the mass of nitric acid, we obtain:

Nitric acid's molecular weight is 63 g/mol.

Nitric acid equals 0.652 moles = weight of nitric acid/ 63

weight of nitric acid= 41.076g

Equation 1 is solved for the following values:

We use the equation: to determine the experimental yield of nitric acid.

0.652=experimental yield / theoretical yield * 100

Theoretical yield = 41.08 g

60%= experimemtal yield/ 41.08*100

Experimental yield= 24.648 g
