Question

3 Cu + 8HNO3 g 3 Cu(NO3)2 + 2 NO + 4 H2O

In the above equation how many moles of NO can be made when 83 moles of HNO3 are consumed?

Answer 1

To determine the number of moles of NO produced, we need to use the balanced chemical equation and the stoichiometric coefficients.

First, we need to identify the stoichiometric coefficient of HNO3 in the equation, which is 8. This means that 8 moles of HNO3 react with 2 moles of NO.

To find the number of moles of NO produced from 83 moles of HNO3, we can use a proportion:

8 moles HNO3 / 2 moles NO = 83 moles HNO3 / x moles NO

Solving for x, we get:

x = (2 moles NO x 83 moles HNO3) / 8 moles HNO3

x = 20.875 moles NO

Therefore, 20.875 moles of NO can be made when 83 moles of HNO3 are consumed.
