Web22 feb. 2024 · According to the equation, 3 moles of NO2 produce 2 moles of HNO3. Next, we use dimensional analysis to find the answer: 0.978 mol of NO2 (2 mol of HNO3/3 mol of NO2) = 0.978 (2/3) mol of HNO3 = 0.652 mol of HNO3. The answer is that 45.0g of NO2 produce 0.652 mol of HNO3 according to the reaction as shown.
