Calculating the Volume of Oxide and the Mass of Water Needed to Obtain 240g of 5% Nitric Acid

To calculate the volume of oxide and the mass of water needed to obtain 240g of 5% nitric acid, we can use the following steps:

1. Determine the Chemical Equation: The chemical equation for the reaction that produces nitric acid is essential for the calculation.

2. Calculate the Molar Mass of Nitric Acid: This step involves determining the molar mass of nitric acid, which is crucial for further calculations.

3. Use the Percentage Composition: Given that the nitric acid is 5% of the total mass, we can use this information to calculate the required quantities of oxide and water.

4. Calculate the Volume of Oxide and the Mass of Water: Using the information obtained from the previous steps, we can calculate the volume of oxide and the mass of water needed.

Let's proceed with these steps to calculate the required quantities.

Step 1: Determine the Chemical Equation

The chemical equation for the production of nitric acid involves the reaction of nitrogen dioxide (NO2) with water (H2O) to form nitric acid (HNO3).

Step 2: Calculate the Molar Mass of Nitric Acid

The molar mass of nitric acid (HNO3) can be calculated by adding the atomic masses of its constituent elements: hydrogen (H), nitrogen (N), and oxygen (O).

Step 3: Use the Percentage Composition

Given that the nitric acid is 5% of the total mass, we can use this information to calculate the required quantities of oxide and water.

Step 4: Calculate the Volume of Oxide and the Mass of Water

Using the information obtained from the previous steps, we can calculate the volume of oxide and the mass of water needed to obtain 240g of 5% nitric acid.

I will now proceed with the calculations based on the provided information.
