Here are the essential concepts you must grasp in order to answer the question correctly.
Density
Density is defined as mass per unit volume, typically expressed in grams per milliliter (g/mL) for liquids. It is a crucial property that helps determine how much space a given mass of a substance will occupy. In this question, the density of the HNO₃ solution is provided, allowing us to calculate the volume of the solution using the formula: Volume = Mass / Density.

Mass of the Solution
The total mass of the solution is the sum of the masses of its components. In this case, it includes the mass of HNO₃ (70.0 g) and the mass of water (130.0 g). Understanding the total mass is essential for calculating the volume of the solution, as it directly influences the density and the resulting volume when combined with the density value.

Volume Calculation
Volume calculation involves using the relationship between mass, density, and volume to find the total volume of a solution. The formula used is Volume = Mass / Density. By substituting the total mass of the solution and the given density into this formula, one can determine the total volume in milliliters, which is the final goal of the question.
