A scientist is mixing two solutions. The first solution has a concentration of 5% salt, and the second has a 15% salt concentration. If she mixes 200 mL of the first solution with 300 mL of the second, what is the final concentration of salt in the mixture?

A scientist is mixing two solutions. The first solution has a 5% salt concentration, and the second has a 15% salt concentration. If she combines 200 mL of the first with 300 mL of the second, what concentration emerges in the final mixture? This practical question reflects growing interest in data-driven decision-making and chemical blending, especially among individuals exploring programming, environmental science, or everyday problem-solving. With precise mixing calculations behind the scenes, this process offers a window into accuracy and logic—principles increasingly relevant in science, engineering, and digital experimentation in the United States. Understanding how concentrations combine helps build confidence when navigating technical or intuitive solutions. ### Why This Topic Is Gaining Attention Across the U.S., curiosity about basic science and practical chemistry is rising, fueled by educational content, DIY projects, and cooking science communities. Mixing solutions with known concentrations isn’t just lab work—it’s a foundational concept used in everything from nutrition science to software simulations modeling concentration dynamics. As accuracy and evidence-based thinking become favored in public discourse, real-world examples like this one resonate deeply with users seeking clear, reliable insights. The question isn’t about spectacle—it’s about clarity and application, making it a natural fit for mobile-first discovery. ### How It Actually Works
